The best solution is to know, or befriend, someone who works at Facebook (you’re in the right forum to meet people).
The short: FB has an internal team dedicated to helping friends of employees fix account issues and they work very quickly.
I know, and have personally used, this service a few times and it’s super useful. (Sadly I don’t work for the company so I’m not helpful here.)
So if you know a FB/Meta employee, contact them about the “oops” team.
If you don’t know anyone, there’s a chance someone here could help (it is extra work for them and they’re putting their reputation on the line so think about how you can show/prove you’re a good actor.)
I’m going to guess that this isn’t helpful to your situation right now but perhaps you can use this info to find someone who can help. Good luck!
