Like the title says , it crashes when launching in 1.16.5 fab.
Other versions such as 1.18.2 works but not 1.16.5.
Does not matter which fabric 1.16.5 version , it crashes.

Here is the error message (if that helps):

The game crashed whilst initializing game
Error: java.lang.RuntimeException: Could not execute entrypoint stage 'main' due to errors, provided by 'mca'!
exit code : -1

Also if anyone got the same issue , how did you fix it?

Please add the full log!
