That's not the first time I see that issue on my test world:
[Server thread/ERROR] [net.minecraft.util.thread.BlockableEventLoop/FATAL]: Error executing task on Server

It generally appears either when I join the world or at the random moment some time after.
Although, it doesn't lead to a crash or anything, I just wonder if it's critical.
My only guess to errors with data fixer (as far as I understand what it is) can be addressed to Tectonic mod, which was reworked quite recently and is expected to have some issues, which I didn't encounter, I guess.
I also have the compat packs for the respective mods:
Previously I had issues with Visible Traders mod that was freezing the internal server for 15 long minutes due to some trader maps issues, but I removed it a long time ago and thi test world was newly created without it.
I just created three new world, flew around for some time and teleported to random RS structures via /locate and didn't see the same error neither when joining the world nor some time after.
So I consider it's just with the test world. Maybe some mod updates did something to it. Last time it was created was about two weeks ago.
