Note: Our team is currently working on solving this bug.
These are the steps to avoid restarting your Kicad v6.0 when attempting to add parts:
In the File Explorer on your computer, go to the following location:
C: > Users > Your computer name > SnapEDA KiCad Plugin > Kicad Library
Right-click on the “SnapEDA Library.pretty” folder and select “Copy as Path”
In your KiCad program go to Preferences>Manage Footprint Libraries.
4. In the Footprint libraries window, select Global Libraries, and on the Library Path for the SnapEDA Library paste the path you had copied in step 2 and then click OK.
Now the footprints you add from the SnapEDA Desktop App to your KiCad 6 will be automatically saved into your Footprint Libraries.
