When I go near a chunk that has a stronghold the games crashes and I get a IllegalStateException: Missing registry error.

Full crash log:

@UsernameNotActive can you remove notenoughcrashes and performant first? Then put on Blame mod and get the crash again. Then show us the latest.log file from the config folder instead of the crashlog file. This will tell us all the information we need
