The addon <unknown> is causing the Couatl Scripting Engine to restart

[miki3320]

Hello, I have a problem with GSX in P3D v5.4 (using it for the FsLabs Concorde), until yesterday it was working fine now when I load into the flight it tells me "The addon <unknown> is causing the Couatl Scripting Engine to restart". I tried to uninstall it and reinstall but got the same error again. I have also the error log if you want. I don't know what to do 🙁

Yes, it's exactly the same error that I have. Hopefully Umberto can fix this ASAP because the FsLabs Concorde is just unusable without GSX

Hello, I have a problem with GSX in P3D v5.4 (using it for the FsLabs Concorde), until yesterday it was working fine now when I load into the flight it tells me "The addon <unknown> is causing the Couatl Scripting Engine to restart". I tried to uninstall it and reinstall but got the same error again. I have also the error log if you want. I don't know what to do 🙁

Having read this I’m so relieved I didn’t run the updater. I still have the slow fuel load problem but at least the aircraft is flyable.

Hopefully @virtuali will fix this problem asap.

[virtuali]

The problem is fixed now.

Confirmed. Thank you!
