@Kitze95 Do you have mods or CC in your Mods folder? If so, do a "vanilla" test to see if a mod/CC is your problem: Move (not copy) the Mods folder to the desktop (or rename it), delete the file called localthumbcache, open the game to test, and exit without saving.
Please also upload the actual Last Crash file. I can't read it, but QA would like the file for future reference.
If you have a Better Exceptions error file, an MC Command Center error file, or a last exception file that was generated at the time of the crash, I'm happy to also look at those.
