Flair crash problem! help needed!

When I use flair recently it has the problem of quit unexpectly, it quits when I change the parameters or save, it quits when I switch tabs, basically anything I do cause the software to stop working, yet it works perfectly fine two weeks ago.
My system is Ubuntu 20.04
Flair version is 3.1-15.1

Dear @ytsun,

given that Flair was working for you previously, the issue is with your system. Which would make to solve it remote very difficult if not impossible.

The only suggestion I can give is that you could try to reinstall Flair. If it doesn’t work, you should ask IT help locally.

Cheers,
David

Dear @ytsun,

could you provide step-by-step instructions how to reproduce the crash?

You mentioned that it was working a few weeks before. What changes did you do to your operating system?

Cheers,
David
