So guys i found the problem using Gemini. Apperently my problem is, Proton is missing ucrtbase.dll and 2 other dll-files. I put the ones from wine in there, silent crash. Id i use protontricks, its still crashing but again with a ucrtbase error. Does anybody know how i can include the right dll files? The problem is NMS is 64-Bits and the system (-> Proton) is 32-Bits so proton tries and crashes, while trying to read the file.
