Cant install windows after getting BSOD

I left my pc on for 2 days and it bluescreened. It would boot up afterwards and i could even use and open apps for for some time till it stopped working entirely. Booted to either repair screen or BSOD with error code: "CRITICAL_PROCESS_DIED". Attempted to clean the SSD fully, wouldn't work. Got error message: ":IO1_INITIALISATION_FAILED; KERNEL_SECURITY_CHECK_FAILURE". Wiped the ssd via commands. Now it kept crashing the windows installation and repair didnt work either. What I have tried so far:

• Installing windows via 2 different Boot USB (formatted it to ntfs), would either say that installation failed or crash at 14-15% and give a couple different error codes : "0xc000021a (0xC000021A)", "SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (0x7E) What failed: Ntfs.sys"; "KERNEL_SECURITY_CHECK_FAILURE (0x139)", "SYSTEM_SERVICE_EXCEPTION (0x3B)".

• Different commands which all led to nothing

• New RAM and switching slots/sticks, installation would fail or go to Recovery screen (when using 1 stick only) with "Your PC needs to be repaired" File: \windows\System32\drivers\bfadfcoei.sys Error code: 0xc0000221. No matter what option i would choose it would flash black screen and go back to the recovery screen.

• New SSD, wouldnt work. Tried the it with a Rufus Boot FlashDrive - either crash or same error messages.

• Reseating the CPU

• Checked all the cables and replugged them

• Updated BIOS to the newest version (3636)

Thinking it might be the Mobo or CPU, but before buying even more stuff i wanted to ask first My specs:

CPU: AMD Ryzen 5 3600

GPU: Geforce 3060

Mobo: ASUS TUF GAMING B550-Plus

SSD: Samsung EVO 990 Plus 1 TB

RAM: Corsair Vengeance 16GB DDR4 3200MHz

Bought pc around 4 years ago

Thank you for any kind of advice and help!
