Telegram group calls connecting problem

Since one week, maybe less, I have problem with Telegram. When I start group call is just connecting but not connecting. Individual calls work.

I suspect that this has something to do with latest Fedora Kinoite updates. My previous update is …520. I updated today because I hoped that things would work again.

My wife has similar configuration but FK … 510 and everything still work.

My Telegram version is 5.14.3

Latest working Telegram on Fedora Kinoite is 5.11.3.

Temporary (or not so) solution - Use Materialgram app.

What package? What is the source? As I could read in a other topic there is no official Telegram version for Fedora?!
I used the web app.

Please complete your request with the information above, so we can try to reproduce.
