Error at startup MythicMobs v5 plugin.5.1
Hello, I ran into such a problem that when launching the current version of the MythicMobs v5 plugin.5.1 an error occurs in the console. The version of the Spigot server is 1.16.5, the version of the MythicMobs v5 plugin.5.1. It starts with Java 16. I attach the error below.
Also before that, I read that it was possible that a virus infected my files, and rechecked javassist did not turn out to be in the log error, I also tried to run on a completely new server with a newly downloaded kernel, on another virtual machine.
