I'm the owner of a file but it's not in a project and I can't move it

I searched for this specific issue, and there was a similar question that’s been closed but in that case, the person wasn’t the board owner. In my case, I AM the board owner, yet I can’t move the board, and when I try to open it’s project I get an error that the project is non-existent.

Maybe somehow it’s been orphaned? How do I fix this, I need to put it into a project.
