Have you tested your RAM health using Memtest86 from Grub?

I did not. I also mentioned in the reddit post that these issues are not new, but I struggle with them for a long, long time. I replaced the RAM a bunch of times and tested it a bunch of times too. I'm pretty sure it's not faulty hardware.

I can check it once again if you want, but when I'm not using the computer.

The test is running for 13 hours now, 11 passes without errors. How long should I run it? In past I only did one or two tests, so I decided to run it for longer this time.

I had to use memtest from a liveusb because after opening the one on my disk I only hear a purple screen and nothing happens, after turning off the computer and back on again it checks the drive for errors, once it couldn't mount it or something and I could skip mounting or try again.

I stopped the test after running it for 49 hours. 43 passes and no errors.
