Where is viaversion installed on? If you put it on the proxy, remove it from there and instead install it on all backend servers.

I only installed on backend servers

I also have this problem, we also only install viaversion on the backend servers. It happens mostly when player switches between servers with different versions, for example 1.20.4 server without viaversion to 1.17.1 server with viaversion. And only in clients under 1.20.
