Exception thrown when trying to open a new file if the last opened file/folder has been deleted

Describe the current behavior

When I try to open a new file (by clicking on the "..." button on the top right), I get an exception:

If the last opened file has been deleted, but the window still opens so I can choose another file
If the folder containing the last opened file has been deleted. In that case, another exception is thrown and the window does not even open so I'm stuck until I recreate the folder

Describe the expected behavior

In both cases, no exception should be thrown and the window should open in any case (by default, in either the user's home directory or the project's directory)

Describe the steps

Open the diagram viewer
Open a file in some specific folder (that you can delete later) --> this works
Delete the file
Try to open another file --> Exception thrown but the window opens
Delete the folder
Try to open another file --> Exception thrown and the window does not open

Environment

No response
