Toon Boom Freezing Problem

Harmony keeps freezing when I click on a key frame .
I tried rebooting and closing and re opening the software still having the same problem. Any suggestions?

My problem is similar, as soon as i click ‘create scene’ it loads up and closes immediately.

I’m having the same problem I’m on windows tho. I havent even been able to get past drawing for a second. Has this been resolved?
