Constant BSOD after about 3-5 minutes of booting

This problem has now been like this for months and I was trying to find a solution to this. The error codes are seemingly random; Namely, CRITICAL_PROCESS_DIED, UNEXPECTED_STORE_EXCEPTION, SYSTEM_SERVICE_EXCEPTION and KERNEL_DATA_INPAGE_ERROR from what I remember. Here is everything I have tried so far-

• Updating old drivers (that did fix a lot of error messages but not all. And it certainly didn't put a stop to the BSOD)
• Installing and reinstalling the latest Windows updates (including the optional ones)
• Scanning for corrupted hardware from multiple methods
• Disabling a few startup apps, including my anti-virus
• running virus and malware scans from Avast and Malwarebytes
• first enabling UAC and then disabling it because it didn't help, although doing that raised an issue of its own (it seems)

Now almost every app is unable to save files to the PC without my permission and it seems that the security settings have been ramped up without my knowledge, not allowing anything to do anything on its own (I have no idea how it works)

Before the permission problem, the BSOD was still the same but event viewer logs showed some error messages relating to luafv. Enabling UAC seemed to fix it and even after disabling it now, I don't see any log messages about it. Now, there are mainly three types of red error messages in the event viewer logs-

Error: "The previous system shutdown at (time) on (date) was unexpected.", Error: "Dump file creation failed due to error during dump creation." and Critical: "The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.".

Apart from the red ones, there are also quite a few yellow ones saying something like Warning: "LSA package not signed as expected", Warning: "The driver \DRIVER... failed to load for the device USB\VID...", Warning: "Credential Guard and/or VBS Key Isolation are configured but the secure kernel is not running; continuing without them." and a few others.

Also, my Windows minidump folder is empty.

This problem (after it started) has never really been fixed. If I get lucky, it would last for a good amount of hours before inevitably going into a BSOD but for the most part, it is just me trying to fix the issue while constantly getting BSODs and having to start all over again every 5 minutes or something.

I am trying to run the Startup Repair Tool from the recovery settings of advanced startup (whatever it's called) and it lands me on the recovery key page (BitLocker I assume), where I correctly enter mine and double-check only for it to tell me that it's invalid. This exact same key has been working perfectly fine earlier and on the website aka.ms/myrecoverykey, it still is the same key

Right before it crashes, I head the audio buzz if one is playing and my cursor behaves weirdly then stops

Here are my specs if that's necessary-

Windows 11 Home 22H2, Lenovo Ideapad, 512GB SSD (no partition), 8GB RAM, AMD Ryzen 7 4700U with Radeon Graphics 2.00 GHz Processor
