I'm stuck with the music playing the logo showing. I can't even get to the menu.

Same here.

I found a unity log located in C:\Users\<Replace with User>\AppData\LocalLow\Owlcat Games\Pathfinder Kingmaker



Plugins: Failed to load 'C:/Program Files (x86)/GOG Galaxy/Games/Pathfinder Kingmaker/Kingmaker_Data/Plugins/GalaxyCSharpGlue.dll' with error 'The specified module could not be found.

But I have that dll in that folder.
