I have the same problem. I tried connecting to versions 1.21.1 and 1.21.4 using viafabricplus on version 1.21.10, and I got the same error when riding a horse or camel.

same, 1.21.11 client 1.21.8 server

I have checked that, even not using the Mod, the issue still occures, so this might be for mojang to fix

Is the server installed ViaVersion plugin? You can't enter the server with different version without that unless you installed ViaFabric or ViaFabricPlus mod.
