I am also getting this randomly since the last MSFS AAU2 update at any airport. Does not occur every time.
When it happens the menu in the toolbar is showing GSX as active.
Today I also got the unspecified add on preventing Couatl from running, and the panic log started and says:
(Running latest update of GSX Pro.)
Not sure if these two issues are linked.
