Any idea why is my video set to private and I can't get it to public again?

I had uploaded a video of my recent flight, it was well received for my amount of views/likes, and then a couple of days ago when I was posting a new one, I noticed it was set to private and I can't set it to public anymore as it always changes back to private after a few seconds.

I wrote to Tiktok immediately upon realizing, but haven't heard anything back. Does anyone know what might be the cause to this? I have the same vid on my other social media, with the same text and hashtags, without any issues whatsoever.
