Anyone who is has a crash on start please try start parameter -safemode
. This will disable plugins and the client may be usable again. Now you can remove 3rd party plugins and maybe the client won’t crash when you remove the parameter again.
On Windows make a right-click on the shortcut you usually would use to start the client and then select properties. Then add the parameter as shown.
Linux/Windows users can add this parameter into the console in case they start the client that way.
