Normally, when you're asking people for help, it's customary to provide a little more information about your PC and how it's failing. See here:
Blue Screen of Death (BSOD) Posting Instructions - Windows 11, 10, 8.1 and 8 for example.
Also, why did you say Windows 11 in the title? You're still running Windows 7!?
Code:
Host Name: EDMUNDAS-PC
OS Name: Microsoft Windows 7 Ultimate
OS Version: 6.1.7601 Service Pack 1 Build 7601
OS Manufacturer: Microsoft Corporation
Not only is Windows 7 no longer supported by Microsoft, and so is thus at greatly increased risk of malware infection, but it's also at greatly increased risk of being assimilated into a botnet, without you being aware, and used to launch criminal dDOS attacks against companies and organisations on which we all depend.
All that said, the one dump you provided shows that an open-file operation was in progress - not necessarily to disk, at a high level Windows sees most I/O operations as file operations - and the call stack contains a call to Bprotect.sys...

...this appears to be a driver for Baidu Antivirus, a free antivirus system that seems be be developed in China(!). That's not the sort of system on which I would rely for antivirus protection, and certainly not in a US based system.
You're also running a driver called mpfilter.sys which is part of Microsoft Malware Protection, and that driver also appears in the call stack...
Code:
fffff880`074672c0 00000000`00000001

Running two real-time antivirus engines is known to cause problems and sometimes BSODs, Microsoft themselves recommend not running other antivirus products alongside Microsoft Security Essentials...
Before installing Microsoft Security Essentials, we recommend that you uninstall other antivirus software already running on your PC. Running more than one antivirus program at the same time can potentially cause conflicts that affect PC performance.
I would suggest uninstalling Baidu Antivirus.
