What is your Shotcut version (see Help > About Shotcut)? Is it 32-bit?
Shotcut version 21.03.21
Can you repeat the problem? If so, what are the steps?
(Please be specific and use the names as seen in Shotcut, preferably English. Include a screenshot or screen recording if you can. Also, you can attach logs from either View > Application Log or right-click a job and choose View Log.)
It happens a lot but not always.I have file that exhibits the problem. When I attempt to change the zoom setting in the Size, Position, Rotate filter that little blue circle appears and after a few seconds shotcut vanishes from my screen. Pataudi Title Clip 1.mlt (11.8 KB)
I reproduced this in that version using your project file with my own media, but it has already been fixed in a newer version. The latest version is 21.06 (your project does not crash for me) even though it has not yet become the recommended stable version on the download page (it might become recommended).
You can also try the beta version for the next release due by the end of the month:
