Gsx pro always crash when I start the game

[Xinsheng]

It sent a panic: the addon unknown is causing the couatl scripting engine to restart
the log is:

couatl v4.8 (build 5341)
panic log started on Sun Jan 28 19:58:29 2024

problem raised by addon <unknown>
Traceback (most recent call last):

It always crash when MSFS starting (I did not enter the game, just duing the MSFS starting and loading for a long time)
My MSFS version is the latest and I run normally before.
I deleted gsx pro and reinstalled it but it did not work.
thanks for your help

When I try Live Update to recover it, live update paniced that “You canceled the Download of this package"，
accually I did not do anything and the connection to the server seems not good because the terminal sometimes shows me 503
but generally I am able to connect to the server and donwload sometiong

oh, when I dismissed the panic from live update, it crashed too.
Live update also dismissed.

You have a failed update, likely caused by your internet connection.

Be sure you complete an update, and use a VPN eventually. Also, try the OFFLINE installer, this will at least get you the latest code, that should fix the error.
