Same here, thought it was just me. Issue is the error comes up on loading and you cant shut it off as couatl script engine continues to want to start. GSX Pro is unusable for me at the moment and have to turn it off all togther. Have done 'live update' which didnt heklp.
Here is bottom of couatl.log file
