Game doesn't run, crashes after last starting logo, GOG Overlay popup visual becomes frozen with a glitched out copy of itself behind itself, stuck in infinite loading and any key press causes crash.

"Remains.exe is not responding".

Tested without Galaxy as well and no change.

If this can't be fixed in the next couple days from posting this I'm just gonna have to refund.

The dev "Lonely developer" shared a workaround on Discord:

Delete "AkMotion.dll" in "\Remains\Remains_Data\Plugins\x86_64\"

That fixed the problem.
