I can't open audio loudness in scopes!

Bug
1

When I open Shotcut, I go to view and scopes. When trying to display audio loudness, Shotcut crashes and closes automatically. What’s occurring? Can someone help me?

2

what version, what OS?

3

Windows 11; Shotcut Version 23.09.29

Does the crash still occur if you try to open it without any clips open?

If you open file explorer, you can browse to the application log:
C:\Users\your-user-name\AppData\Local\Meltytech\Shotcut\shotcut-log.txt

Immediately after a crash, do not re-open Shotcut. Then, find this log file and upload it here. Maybe there is a clue in the log.

I reproduced it on macOS

With or without something loaded.
The funny thing is that the Audio quick layout switcher that includes this scope is working for me. And then when I switch back to Editing I can open the scope in that layout now without crash. And now when I close and start Shotcut with that scope in that layout, it still works.

This is fixed for the next version.
