Hi, sorry to hear about the issue. It appears your profile.sav file got corrupted. You can fix this by deleting the file. It is located it here:
C:\Users\[your username]\AppData\Roaming\Void_War
By the way, do you have any details on how the profile.sav may have been corrupted? Perhaps by force quitting the application or terminating the process? Or perhaps power loss or Windows crash?
