Ok. It seems to be the messed up RAM stick. It's opening projects now.
But it's being really slow... I'm running the benchmark now. It's not like the loss of one stick took me very low in RAM. In fact I have 16gb over the 8gb the PC came with that I initially tried the benchmark on when I got this thing.
Back then It was like about 14 and a half minutes.
Edit: So 16:24. I'm not on the new update, so it shouldn't be that. I'm thinking it's either performance loss in Windows 11, or the fact Ryzen CPUs have to emulate TPM, which is a constant thing. I've already read it can cause never-ending video and game stuttering, but I don't have those issues, thankfully on the 2600.
