btw , Im playing ate 1.16.5 forge version

Try deleting your Better Strongholds config. It's hard to tell exactly what the issue is from these logs, and unfortunately I don't provide support for 1.16 versions anymore. But you can try asking for help in the Discord, there are plenty of people in there that may be able to figure out the problem.
