Lost Access to my own Board

I lost access to a board that is critical to my work. I feel like I’ve tried everything getting it back: getting added back to my university team (which I don’t think it was under originally anyway) upgrading to a paid account and checking my trash, requesting access using the direct link of the board (which I was the owner so the request would come to me theoretically?). I’m at a loss. Support has not been helpful at all.
