Description
What is the bug or the crash?
When I attempt to open a print layout in my project, QGIS crashes with the following traceback:

Steps to reproduce the issue
This crash seems easy to reproduce:
- Add an DEM layer to your project
- Create an elevation profile
- Create a print layout
- Add an elevation profile to the print layout
- Populate it by using "copy from elevation profile"
- Remove the elevation layer from the project
Now QGIS will crash when you attempt to open the print layout.
If the data required by the print layout is missing, it should render an empty elevation profile and log an error rather than crashing.
