Try to boot your computer into Safe Mode if you cannot, then boot your computer with Windows Setup Media and from Windows Recovery Environment and use System Restore tool to restore Windows 10 to date when there was no error.
From Windows Recovery Environment, try Startup Repair tool.
From Windows Recovery Environment, type below command into Command Prompt and press Enter key.
The following command scans integrity of all protected Windows system files and repairs files with problems when possible.
Please replace partition letter C: with Windows installed partition letter. When the computer boots into Windows Recovery Environment (WinRE) environment, the drive letter assign to Windows partition may not be C: drive letter because Windows 7, 8 , 8.1 and 10 creates a separate system partition when it's installed from scratch. The system partition contains boot files WinRE assigns the system partition the C: drive letter and the Windows installed partition will be assigned any other drive letter, usually D: drive letter is assign to Windows installed partition. The Bcdedit | find "osdevice" command can be used to find out the drive letter of the Windows installed partition, the output of the Bcdedit command is similar to this osdevice partition=D:. The drive letter after partition= is the drive letter of the Windows partition.

This is also another perfect example of Why you MUST Routinely Take Full System Image Backups of Your Computer.
There are just so many occasions where trying to fix an issue takes so much more time and effort, and can often fail. Keeping full system image backups at an interval dictated by how much data you create that you would not want to lose is the easiest way to prevent this.

I realize this will not help at this juncture for this specific situation, but it certainly could prevent any future ones like it.

Are you using a USB device?
If yes, try another port.
And 90% of the time I had issues installing Windows (after confirming the install media was OK) it was problems with the HDD or SSD.

I would take a look at what CrystalDiskInfo is telling you about the state of your system drive as a first step. If you happen to have a bad drive that could be the root of all your issues.
If that shows clean, whenever inexplicable issues present themselves “out of the blue” and with seemingly no reason, these are the two things I try first, in order:
1. Using DISM (Deployment Imaging Servicing and Management) and SFC (System File Checker) to Repair Windows 8.1, 10 & 11
2. Performing a Windows 10 or 11 Repair Install or Feature Update Using the Windows ISO file
If #1 fixes the issue, #2 is unnecessary. If either one of the two utilities in #1 fails, still try running the other.
If neither of those work, then it is on to
Doing a Completely Clean (Re)install of Windows 10 Using Media Creation Tool to Fetch the Win10 ISO File
or
Doing a Completely Clean (Re)install of Windows 10 Using Media Creation Tool to Create Bootable Win10 Install Media on a USB Thumb Drive
depending on how you want to create a fresh copy of the Windows 10 install media.

I can't use Crystal Disk Info because I can't boot up and I don't have Windows on my drive. I can't clean install because it gets stuck in some point and just shows the error again.

How did you create the Windows 10 USB?
You can use Windows 10 Media Creation Tool if you haven't.
Download Windows 10

Then you almost assuredly have a bad system disk.
If you know you have fresh, clean install media everything that is needed for a successful install of Windows 10, even if you are not connected to the internet, is present.
If you have gotten this error 2 times, and have used two different copies of the install media that you have no reason to believe are bad (or know are not bad because they've been used to clean install on another machine) then hardware problems, and most likely drive problems, are at play.
Hence the reason for my advice in Post #3 of this topic. These things, particularly drive failures, can and do happen. And having to get a new drive, do a completely clean reinstall, and rebuild your entire Windows computing environment from scratch is far more time consuming, and energy (both physical and emotional) consuming, than doing a restore from backup is.
If someone has a suggestion for a bootable disk checking utility, then please offer it so that the OP can do a thorough disk check, then please share it.

Run Seagate SeaTools
SeaTools Bootable provides a basic suite of diagnostic utilities in an environment independent of your installed operating system. This will allow you to test, diagnose, and possibly repair your hard drive, even if your operating system environment is inaccessible.
Please download and use the SeaTools Bootable to create a bootable USB that you can use to diagnose hard drives and monitor SSDs.
The flash drive must be at least 256 MBs but no larger than 32 GBs.
Use SeaBoot_11-18-2019_RC5.usbBootMaker.exe to create bootable USB.
1. Insert the SeaTools USB device and reboot or power on your computer.
2. After SeaTools loads, the Drive List will show different storage devices in your system. Select the drives you would like to test.
3. The menus provide an array of diagnostic tests. Select the test you would like to perform on the selected drives. Please click on Long Generic Test. Long Generic Test scans the entire drive for defects. It will take a long time to complete. Because this test reads every sector on the drive, the amount of time required will depend on the speed and capacity of the disk drive. The highest capacity drives often take 3 to 5 hours per terabyte to complete. At any time, feel free to Cancel the test without harming the drive. Long Test is completely data safe.
4. The test will indicate either Pass or Fail. Upon completion of running the diagnostics, the test results will be given. A log for each device is automatically saved if you have booted from a USB device. Test results are automatically saved in a log file with a file name based on the drive serial number. Post the results of the scan in your topic.
