(I dont know how to update my earlier comment, sorryy)

Update: I found the cause of the issue.
It was caused by the saved structures in the worlds database. I had at least 50 very large structures saved, with sizes of up to 64×300×64 blocks. After removing the saved structures, the Editor loaded normally again and all tools and features became available.

This seems to indicate that having too many or too large saved structures can cause the Editor to hang while loading, resulting in the error and preventing the tools and other features from loading.

I can confirm this issue on version 26.44.

I recently tried to open one of my creative worlds in Minecraft Editor, but only 6 tools were available. The following errors appeared in the logs:

[Scripting][error]-[resourcePack.editor.server.name] InternalError: interrupted at e (@minecraft/server-editor)

[Scripting][error]-[Watchdog] 13665 ms hang detected in 'resourcePack.editor.server.name'

While the world was loading, Minecraft used more memory than usual and it took longer than usual. After joining the world, the Editor GUI was completely unresponsive. I could not save and exit the world or select any of the other tools.

After 12-14 seconds, the errors appeared in the logs and the GUI became responsive again. However, only the 6 tools were available.

Additionally, many features introduced in newer versions of Editor, such as the Fill Biomes Tool, were unavailable.

I deleted the level.dat file and removed all add-ons and resource packs, restarted the world and the game many times, but the issue persisted and the same error appeared again. I then deleted the .db files (from a backup copy) of the world. After doing so, all Editor tools and features became available again. (While losing all of my builds, saved player data, scoreboard and more due to deleting the whole .db files)

This makes me suspect that either the size of the .db files (~ 2MB) or a specific piece of data stored inside the database is causing the issue.

I hope this issue can be investigated and that a way to fix the affected worlds without needing to delete the entire .db files can be found. I would appreciate it!
