For my time's sake, I skipped the RAM test and went straight into making a second partition on my main drive and trying to install Windows there, using a Windows 10 LTSC 2021 USB I just made using Rufus. The result was a blue screen on WinPE booting, so yeah, it's definitely a hardware issue.

If you were wondering, just because you mentioned Intel CPUs and stuff, my specs are:

AMD Ryzen 5 2600
Corsair Vengeance LPX 16GB @ 3200MHz
MSI B450M PRO-VDH MAX
Samsung EVO 990 1TB (plus an extra 1TB HDD for data)
Nvidia GeForce 1650 Super
550W PSU (I don't remember the brand, I think it was Corsair)

I think I'll just shell out some money for an AM5 upgrade...

As a side-note, since I first booted into WinPE from a crash (I tried to boot into Windows first to see if the issue was somehow magically fixed), I actually did manage to get into it, but I got a "Windows installation encountered unexpected error" error when the installation was finishing. Trying to boot into it again, I got the same "KMODE_EXCEPTION_NOT_HANDLED" BSOD. A very peculiar problem, indeed.
