CLIENT - unhandled error in GUI - IllegalArgumentException

[JacobLoe]

Hi,

for a while I cannot use xmage on my PC. The launcher works, but whenever I want to login or use the deck editor I get the error message below. I tried updating Xmage, reinstalling it and reinstalling Java, neither of which changed anything. It does work on all my other machines/OSs, only one specific Windows 11 PC doesn't work.
