Bonjour,
@Shaba1
I recommend you download this version of G’MIC GIMP :

The update works well with this version.
Tell me if it works on your computer.
@afre
The 2 versions of Gimp (gimp.org and Partha) are complementary but unfortunately neither is perfect or complete.
I hope with all my heart that it will be possible to do something better with Gimp 2.10
