Shotcut stops when using filter on macOS

Shotcut stops when I try to use the function filter.
MAC OS Catalina
Shotcut 19.12.31

This is part of the error message:

What filter are you using, What format/resolution/framerate video are you using. It’s good to know you’re on the latest macOS but what hardware is it running on?

Does this happen when you click Filters on the toolbar? Did it ever work before?

Some macOS users report their Filters window is blank when they make it float instead of docked into the main window:

If this sounds like your problem use View > Layout > Restore Default Layout and try again. Or, you can delete your settings file ~/Library/Preferences/com.meltytech.Shotcut.plist.

This is an OpenGL failure, but it works for me on all of my Macs. If you enabled the hidden, unsupported GPU processing feature turn it off. If you did not, then this is a compatibility issue between the GUI library we use and your system that I will not attempt to fix. Some parts of the Shotcut UI use OpenGL to draw, and OpenGL is notorious for interoperability issues. Either it works for you or it does not. Perhaps in a couple of years when we upgrade to a major new version of the GUI library that uses Metal instead of OpenGL, it will work better.

Yes, I clicked Filters at the toolbar. The window of Filter opens first, when I try to move it to another place, than the program crashs. It worked before. But, sorry, I don’t remember what changed, before the problem started.

I’ve got it! With View > Layout > Restore Default Layout it looks, like it’s running again. Thanks!
