Game keeps crashing
The game crashed whilst initializing game
Error: net.minecraft.class_151: Non [a-z0-9/._-] character in path of location: lang:af_ZA.lang
Exit Code: -1
Need a full log file, but most likely need to reinstall
Do you have tlauncher installed?
because when I ran a outdated version it made my normal minecraft pop that error up but i can run it with tlaunchers new version but only on tlauncher so try that i guess if not you will have to reinstall mincraft
