openshot has started crashing

Xubuntu 20.04.4

As of about a week ago, many programs have stopped working. I believe there was a buggy update that is responsible, although I cannot pinpoint it specifically.

Clutter-gtk seems to have been changed (eliminated ??) which has affected many programs. See my report here:

https://bugs.launchpad.net/ubuntu/+bug/1974254

Today I tried to start Openshot, which I have used withing the past two weeks, and I get the following results. This is a qt app, so it must be related to something else.
