Reference to old disk causes Premiere Elements not to start

Somewhere during startup up Premiere Elements 2020 is searching for a network disk that I do not always have available. So when my NAS located at z:\ is not present the PE refuses to start. I get a screen where I am offered to send a crash report (which I have done but received no feedback).

I have looked through all settings and changed default storage location to my D:\... which is always present. But still somewhere in a setting I am not able to locate there is a reference to this z:\ disk.

The only clue I have is that after start up without doing any other changes and when I do "Lägg till media" and select the "Filer och mappar" (swedish version and I suppose it is "Add Media" and "Files and folders" respectively in the english version") the default location it is opening is "Z:\Stefan\Adobe\Premiere Elements\18.0". And I cannot find where this is configured. So somewhere in PE it is still referencing my "Z:\ disk".

When the z:\ i mapped and available everything works fine. But I am going to retire this old disk and do not want to have it left just because PE needs it to start.

Any hints what to look for is appreciated
