@BISWizard Sorry for late reply, just got some free time to test both of these, simply drag and dropping and replacing any files, sadly though both of these had the same result for me and both instantly crashed when I clicked play on steam. and as for when i was last able to use the Launcher, I last used it the night before 1.68

@BISWizard I had a look and the closest folder I found to the name was Pt-Br I take it this is the one you meant, I deleted it and tried again, same issue, so I deleted the whole Launcher folder. and re-verified my files, let them download and tried again, still crashes instantly
