I had something similar happen to my Instagram account.
A few weeks ago, I got a popup inside IG to verify my age. Not wanting to give them my real age, I set my age as 0. The popup playfully said that my age can't be 0. So I set it to 20 years and the popup got stuck. After a few taps, my account was marked as underage account and I had to send my photo id to get it back else it will be deleted permanently after 30 days.
I though about all the photos and messages in my account and while it would be sad to let it go, I reckon IG's ban was a blessing as the quicker I let it go, the free'er I would be from Meta's clutches.
In in the end, I didn't verify my account. By now, it would be wiped out by a cronjob.

The sooner you realize these companies(and Meta in particular) don't care about you, the better. These are all rented platforms and should be treated as such.
Don't invest too much in these platforms and if you must, invest in a personal blog hosted on your own domain.
