In such a case, add the following parameter to

This parameter forces CloverDX Designer to run using GTK 2 which may fix the problem.
Note: do not use the parameter on systems using GTK 3 (e.g. Manjaro with KDE Plasma 5), as it may cause other problems (e.g. non-functional tooltips in the graph editor).

and perform the following steps:

aaa, create a file

If this message appears, refresh the project in Navigator.
