An error was happened in Fabric Server for 1.21.4

[837cyo84o2rcj]

I have a Fabric 1.21.4(the Fabric Loader Version is 0.16.10, and the Installer Version is 1.0.1) Server. Recently, I met the error "### [Server thread/ERROR]: Can't access registry ResourceKey[minecraft:root / minecraft:game_event]" for more than 8 times in 2 days. This error doesn't influence playing processes. It just laid there, didn't do anything. Here's my server's MODs list. I'm not sure is this error was caused by some of the MODs:

This probably won't help you much, but I am having the same error, and I narrowed it down to SimpleCopperPipes (though I am using the 1.21.1 version)

[837cyo84o2rcj]

After I removed SimpleCopperPipes, the error disappeared. I guess it was because the copper pipes were transferring items too fast, causing the server to be unable to access the registry normally? (I connected 6 full boxes in parallel with copper pipes, and the error appeared immediately)
