• Via plugins are only running on EITHER the backend servers (e.g. Paper) OR the proxy (e.g. BungeeCord), not on both.
• 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.

Please update all Via* plugins from https://ci.viaversion.com/. In case the issue still persists send the new dump and the issue will be reopened

We have encountered the same issue when joining 1.20.1 with 1.20.5/6.

This issue only happens on certain area of the map. When /tp to those area, the client disconnected instantly with "Network Protocol Error". Perhaps it is due to some entities / blocks?

Tested with:
ViaVersion - 4.10.3 build 846
ViaBackward - 5.0.0 build 615

Don't mix dev and non-dev versions. In general, that error means you've got a plugin sending bad entity or scoreboard data, you'd have to remove plugins until it doesn't happen anymore to see which one it is
