Minecraft Version

1.20.1

Describe the Bug

While running the server randomly crashes and continues to crash once a chunk with some entity (not sure what) is loaded.
This was done in a modpack I'm working on. Crash report here https://pastebin.com/xd64g6xt

As a side note I was able to 'patch' this by adding the below in where the crash was happening.

if(blockEntity == null){
    return Blocks.AIR.defaultBlockState();
}

This was just a temporary workaround to get the world to load, I'm unsure if this is causing any unexpected behavior.

Reproduction Steps

The exact repo steps are unknown, this happened upon exploring a world for a while on the latest version

Expected Result

Server Doesn't crash

Screenshots and Videos

No response

I can confirm this exact bug. Just received it myself. I have no idea what's causing it, but there's over half a dozen completely unrelated mods mentioned, and this is the first one mentioned. It is world breaking for me, and I can no longer load the world I played on.

Imcompatible with Computer Craft. I'll figure out a fix.

I feel a better fix here would be to fix DelegatingSmartTileEntity to return a sensible default value for getBlockState, rather than adding mixins to mods that call getBlockEntity within AttachCapabilitiesEvent.
