I am no GAP animation user, although I do dabble in video. I see that error message, This in a Win 10 VM + Gimp 2.10.8 + Gap (2.6??) screenshot: https://i.imgur.com/9fbs6CO.jpg
edit: Those error messages about themes: Try changing from that nasty black theme to maybe the system theme in Edit -> Preferences -> Themes
However, It did import as .xcf files a 10 second clip and it did export those as an avi file. I can see that Master Video Encoder is liable to crash...such is the problem of using ancient software.
The output was surprising reasonable. https://i.imgur.com/rfvkswg.jpg
I just put the GAP folders straight in the Gimp user profile https://i.imgur.com/cHJHN9c.jpg and added the paths in Edit -> Preferences -> Folders
There is a lot of GEGL code in Gimp 2.10, all the editing directly on the canvas is due to it. If GAP worked in Gimp 2.8 I would go back to that version and maybe run a separate Gimp 2.10 alongside. The Partha Gimp 2.10 does not conflict. http://www.partha.com
