It's possible there is a broken library entry causing it to crash. If you go into the directory where the Minecraft/the profile is installed and delete the tails-library.json file, it should then allow you to open it

[DerRoboMeister]

Good, but new problem. All entries change to the tail I have when I try to save them in certain cases. I can fix them just fine buy fiddling around a bit though. Not sure what the exact process is.
