"Something went wrong, please restart the application or try again" - I can´t open the editor.

Since this morning, I’ve been getting the following issue: "Something went wrong, please restart the application or try again"

I can't open, edit, or publish my worlds.

I posted about it on Discord but haven’t gotten any replies, so I’m hoping someone here can help.

We’re just hours away from the end of the competition, and I can’t leave my game in the state it should be in.

The issue happened after exiting the editing mode of a world.
I’m leaving a video so you can see — honestly, it’s really frustrating as a creator to have this happen on the last day of the competition with things still left to finish.
