Same thing here. I did some very limited research on this with Minecraft version 1.21.4 (`2b2t.org` server), it seems to have to do with the "end" packet. If you comment...
Can confirm, same thing happening, it works fine with 1.21.3 but crashes with "Network protocol error" in 1.21.4, similar packet log as the one reported above.
