I managed to indentify who is creating the incompatiblity with MSFS 1.36.2 , both files init.py, if the developper isn't interested in providing a solution to restore the function of the plugin, I would understand.
On this thread someone mentioned lack of compatiblity with other 3rd party if I don't update msfs, well the issue is occuring only with GSX and the other 3rd party devs don't force you to update plus msfs 2020 is no longer going to get huge updates I guess with msfs 2024 in less than 6 months. It would have been cool to still be able to use gsx with the performance I had prior to the SU15
