I have the same problem :
After updating GSX with Universal Installer I still get the error that Couatl engine won't start. I also added the GSX and associated files to the Anti-Virus exception list. Always the same.
When starting the message comes: GSX regenerating Airport Cache (67%) please wait... Then again the Couatel engine does not start. The following error:
couatl v3.2 (build 4641)
panic log started on Wed Mar 2 17:06:15 2022
problem raised by engine or unspecified addon
{'Airport': 'rpll', 'user pos': (14.50461553669277, 121.0020153221283, 26,3502 m, 3,49023 m, 275.07254108227414, 0.016184519976377487, 0.005580201745033264, 0.0, 3.5381520584106445, 1.0)}
Before the update GSX ran without errors, I already had the new update with the Walk-In Gates which ran without any problems.
Nothing has worked since last week.
My Simulator : P3D v.3.
With FSX and P3d v.5 GSX runs without problem.
But P3D v.3 is my default simulator because I have most addons for P3D v.3.
I hope you have a solution for me
regards
