Error when joining server on 1.20.6

[Jesper-Hustad]

When I try using the 1.20.2 version I get an error when joining a server running on 1.20.6 without the syncmatica mod.

Is this something that can be easily fixed?
(I know java well, but new to fabric and mc mods)

1.20.2 will not work with 1.20.6+
