Crash when duplicating a layout

[Energeo1]

What is the bug or the crash?

When I want to start editing a layout that I just duplicated, QGIS gets stuck for a moment and then crashes.
This happens often with any project I am working on.

Here ar the Report Details:

Python Stack Trace

Steps to reproduce the issue

1. Create a layout in your project
2. Duplicate the layout
3. Try editing the duplicated layout

@Energeo1 thanks for reporting. Could you please specify if the issue does occur every time a duplicated layout is edited or only some times? Could you please provide a sample project and exact steps in order to replica the issue? Have you tried if the issue does occur using a new QGIS user profile with no external plugin installed?

[Energeo1]

@agiudiceandrea thank you for your feedback!

Strangely the issue does not occur every time I edit a duplicated layout, only sometimes. Unfortunately I cannot relate the issue to a prior common step, because there is none.
I open the duplicated layout and either zoom in or try to change an inserted element in the map layout and then qgis crashes. Sometimes it also crashes directly without trying to edit anything. Then in some cases the window "QGIS ended unexpectedly" occurs and in others QGIS crashes without any information.
The issue does not occur when using a new QGIS user profile, but unfortunately I cannot get my work done without any external plugins installed.
Creating a comparable example project is difficult because I have a lot of layers, also different layers in the project, and I cannot share the data I'm working with because they are sensitive.
The working flow is the following:

1. Create a layout
2. Close this layout an duplicate it in the layout manager
3. Open the duplicated layout and try to edit

I hope this helps to understand the issue as well.
Does anyone else know this problem?

Thank you!

I've caught a segmentation fault after various attempt to replicate the crash. The following is a gdb backtrace (QGIS built at 3e0517c) which will hopefully help some dev to find the root cause of the issue:
