freeze when save trimmed video

[patrcoil]

Hi, I just installed vidcutter on Ubuntu 20.04 with Gnome. It works fine when trimming a video, but when I save the trimmed video with the "Save media" button, vidcutter freezes with the progression bar, always, at 50%. The only thing I can do is to kill the process vidcutter. However, the saved trimmed video is fine. I executed vicutter with the option -debug. When it freezes it provides on the terminal the following message:
2023-05-12 14:24 - root - CRITICAL - <class 'AttributeError'>: 'VideoService' object has no attribute 'parentWidget'
Can somebody help? Pat
