WinBox window closes automatically when accessing router

I"m using Chateau 5G with RouterOS 7.10.2 and since few days I’m having a funny glitch with using WinBox (Win 11) to connect to it.
Anyway whenever I try to use WinBox (3.39) to connect to my router WinBox instantly closes without reporting any errors. I’ve searched forum and found some users had same issue but none of the provided solutions worked in my case.
I cannot exactly pinpoint when it started happening as I’m not accessing router so often but the last major issue I had with it was for some reason when it froze and I’ve had to reset it to factory defaults and afterwards restored a backup to it.
I haven’t changed any network settings What could I be missing? At least I can still access it via web interface but really don’t understand what happened to WinBox.

Thank you for any ideas.
