Console Error

Bug Description

The server crashes almost immediately when ViaBackwards is in the mods folder. Removing it from the mods folder resolves the issue.

Steps to Reproduce

1. Install Fabric Server
2. Place both ViaFabric and ViaBackwards into mods folder
3. Run the server

Expected Behavior

The server should load successfully and allow 1.20.1 or earlier clients to connect.

Additional Server Info

Using the latest version of mods as taken from Modrinth:

• https://modrinth.com/mod/viafabric/version/0.4.11+49-dev
• https://modrinth.com/plugin/viabackwards/version/4.9.0-23w44a-SNAPSHOT+61

The issue report form recommends Not Enough Crashes so that is included, but I can reproduce the issue without it.

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.

Update to latest via* builds using the ci link, also 1.20.2 fabric servers with fabric api in it is currently busted anyways.
