Bug Description

Joining a 1.2.5 vanilla server will instantly disconnect me if either of the following mods are enabled:

• Vivecraft https://modrinth.com/mod/vivecraft
• Carpet TIS Addition https://modrinth.com/mod/carpet-tis-addition (with Carpet Mod https://modrinth.com/mod/carpet)

Game version 1.20.4, Fabric Loader 0.15.7, tested with ViaFabricPlus v3.1.0 and a snapshot version from the actions page. Tested with no other mods installed other than ViaFabricPlus and either one of the culprits (and Carpet Mod in the case of TIS Addition) I have also joined the same server with over 100 other mods enabled, only when enabling either of those 2 causes me to get disconnected. I can share the mod list if requested.

Steps to Reproduce

1. Install Minecraft 1.20.4, with Fabric Loader 0.15.7, and ViaFabricPlus 3.1.0
2. Install Carpet TIS Addition https://modrinth.com/mod/carpet-tis-addition (with Carpet Mod as a dependancy, note that Carpet Mod does not cause this issue by itself https://modrinth.com/mod/carpet)
3. OR install Vivecraft instead https://modrinth.com/mod/vivecraft
4. Launch the game, select the correct versions 1.2.4-1.2.5 in the Via menu, then join a 1.2.5 server (I tested it with a local server with default settings, downloaded from https://minecraft.wiki/w/Java_Edition_1.2.5)
5. You will be disconnected almost instantly, with the error message "Disconnected" shown as "lost connection: disconnect.genericReason" in the server console.

Expected Behavior

You should not be disconnected and should be able to enjoy happily playing Minecraft with those mods.
