Why am I not seeing the comments on my video in YouTube?

I have notifications for comments on my video and I really want to reply and interact with them but those comments do not appear!

Also the comments counter counts them but they do not show, neither on video page nor in YouTube studio, nor if I choose to see “help for review” comments.

Is this a known issue? Why don’t the comments show up?
