Use OvGME or Open Mod Manager, more user friendly (with OvGME for example you can manage mods in core game and Saved Games with only one "Mods" folder where you want on your PC), and I saw some where JSGME stop working with DCS
In the past this problem was there after an update, and come back usuable later after another update without doing anything, may be ........
Edit: I just make a test with canopy from French Pack V4.8 and ...... same issue
