I found out that today too after having a clean-up. It wouldn't show me old tweets I had previously liked because they are now age restricted and I wanted to see what they were so I gave a DOB which would've made me 23, but they locked my account anyway because that would have made me younger than 13 when I joined. Nuts!! It now wants a parent to provide them ID! lol! Seeing as I'll never provide any ID that's my Twitter / X account gone forever I guess.
