Glyphs crashes while hinting

Dear Glyphs Team,
When I try to drag the hinting circle or the arrow to a point the Software crashes. I tried opening a new document form zero, reinstalling the software without plugins but it didn’t help to solve the problem. I use Catalina at the moment.

What version of Glyphs do you use? Can you send me screencast?

Hi Georg, Thank you very much for your fast reply. I use 2.6.3 version. I have sent you a video showing the problem. By the way the problem doesn’t occur on my virtual High Sierra.
