[split] Gimp 2.10, Resynthesizer, Linux

[Busy B]

I installed resynthesizer and bimp. Additionally I installed some brushes and fonts. I also installed AppImage for Gimp. On Monday evening I got everything running. Yesterday resynthesizer was gone but the rest was still there. My gimp crashed several times today. Suddenly resynthesizer was running but my installed fonts, brushes and bimp were gone. They are still in the folders they should be in but somehow gimp has forgotten them. I have the latest version of gimp running under linux unbuntu 20.04. Has anyone an idea what happened? I don't get it.
