In the 'office' now.
I can see the gmic_gimp focal plugin does not show in kubuntu 20.04 the name does not matter.
Try the one from my storage: https://u.pcloud.link/publink/show?code=...KrvLdF7p0k unzip etc as before
By rights it should not work, it uses the QT libraries from Mint19 Worth a try.
Try deleting the pluginrc file and let gimp scan the plugins again. Might be an old setting causing problems. edit: I see you already did this
edit: refresh the filters as well. Can't think of anything else at the moment. The problem should reallly be sorted out by the appimage maintainer across at pixlus
