What happened?

Forge 47.2.17
MC 1.20.1
Dim Doors 5.3.3

When pregenerating a world, Dimensional doors will cause the world to hang causing a crash. I've attached a thread dump for reference. I have been able to start and stop the hanging just by disabling/enabling dimensional doors. This issue is also present in the previous stable release.

I'm having the exact same problem on my server. It's running Quilt 0.25.0 on MC 1.20.1 with Dim Doors 5.3.3.
The server runs without problems when nobody generates new chunks, but as soon as I start pre generating new
ones with Chunky, it crashes.

I also tested with a small testing modpack on my local machine. Here's the log.
