SKSE64_Loader won't start the game

For some reason when I try to boot my game (which worked fine a minute ago), I get the following instead (also see image below):

SHGetFolderPath 00000005 failed (result = 80070005 lasterr = 00000005)

Assertion failed in E: \github\common\common\IDebugLog.cpp (64): SUCCEEDED(err) (code - FFFFFFFF80070005 (-2147024891))

Can anyone tell me why this is happening, and/or what this means and (hopefully) how to fix it?

What I have tried so far:

Checked the firewall and the antivirus software.
Run as admin.
Re-installed everything around 4 times, including the game and SKSE64.
Checked mod conflicts.
Disabled controlled folder access.

PS when it started acting up, I had just wiped my keyboard real quick and I hit a couple of buttons and then the black screen came up and now it won't work.
