I run X-Plane 11 with Steam on Mac OS 10.15.3 and after installing the G5 instruments my whole X-Plane cannot start. I get the following error message during plugin loading:
X-Plane 11.41r1 quit unexpectedly.
Even after uninstalling the plugin with the uninstaller, X-Plane would still not start. I had to reinstall X-Plane from a backup which took a while.
I was wondering if anyone else is having the same problem?
