Qt shut down itself when I click Design Button

[ucan]

QT Quick Application (QML) doesn't work fine on my computer, when I click Design Button (as you see on video) QT shut down itself. Do you have any idea what can cause this problem?

I use ubuntu 20.4 and I changed ( I removed and installed again and again) qt version several times to avoid this problem but problem still remains.

@ucan Facing same issue currently. Were you able to resolve it then?

@ucan I get it! It's because of some error in the file like module is not supported or the component or type is not recognized. In my case, I removed one of the components then it worked fine.
