I found that Shotcut may crash when I using Mask: From File and Size, position & rotate filters at the same time.
This happened when I use some picture as a mask, but not every png will cause it. And everything was fine when I use the mask filter alone. I made those picture by inkscape, and I don’t know what is the difference between them that cause this bug.
Attached files are some examples, the circle one would cause crash and the another doesn’t.
I’m using version 21.05.18 on windows10 (64bit)
