Checklist

• I have checked if this is specific to ViaFabric platform, and doesn't happen when running it on other platforms (Paper/Sponge/Velocity/Waterfall).
• I have included a ViaVersion dump.
• If applicable, I have included a paste (not a screenshot) of the error.
• I have tried the latest build(s) from https://ci.viaversion.com/ and the issue still persists.

1.20.1 is unsupported.

And how did it start with version 0.4.10+40-main then

Because it has an older version of viaversion but because viafabric dropped support for 1.20/1.20.1 and 1.20.2 clients in favor of 1.20.4, it will not be worked upon until enza starts on the rewrite which has yet to happen.

• for additional note: the reason why it was dropped was because internal classes have changed.
