Hello, and welcome to the forum!
If by a 'clean reinstall of Windows 11' you mean you installed from bootable media, deleting existing UEFI partitions, and you subsequently installed all drivers and updates via Windows Update (until no more updates were found) and you still get BSODs, then you can be pretty certain that your problem is hardware related.
The System and Application logs are missing from your upload. Did you delete them? They are a very valuable source of information, especially in situations like this.
Taken together the dumps strongly indicate that you may have a RAM problem. We're seeing a couple of dumps failing because of bad memory pointers; two fail with 0xC0000005 exception codes (invalid memory reference) and one fails with a 0xC000001D exception code (execute an illegal instruction attempt), this one because of what the dump triage analysis calls 'memory_corruption'. In this dump there is also a CHKIMG failure, these indicate that an executable image is corrupted. That either happens because of bad RAM or because the system drive is bad - given the other failures we're seeing bad RAM is the more likely.
One dump blames the Valorant driver vgk.sys. This is a well-known cause of BSODs and may indeed have caused this particular BSOD. It's not seen in any of the other dumps however, so it's more likely that vgk.sys failed because of the RAM problem we suspect. That said, it may be worth seeing whether it still BSODs if you reboot (to unload vgk.sys) and do not start any games that require Valorant to be running.
Generally we like to see Memtest86 run twice, for a total of 8 iterations, but I won't ask you to do that. Instead it's a more reliable test to remove one RAM stick and run for a while on just one. I realise that this may cause some bottlenecks, but if it BSODs on one RAM stick and not the other then yu have the culprit If it BSODs on both one their own then it's not a RAM problem and we need to look elsewhere
One thing at a time though.
