With the modpack installed, it only works in safe mode. Problem started after updating to 5.4.1. As game opens, and the loading screen appears, it freezes, As it opens an error window. Didnt find any python file in the game folder. Also coundn't print the error screen for some reason, so i had to take a photo. Edit: User Quaksen instructed me on where to find the pytohn log, so I uploaded it
