Title: Couatl64_MSFS.exe - System Error
Post by: BongoBear on December 29, 2025, 03:41:51 am

Hi Umberto,

I've been getting this error almost everytime I load into an aircraft since yesterday. I'm attaching a screenshot so that you know the exact error code.

Regards,

Please post your log here, and don't post the .ini file, but the log itself.

I have the exact same error on 3.7.5. Quite annoying having this pop up in the center of your screen on short final  ;)

Code: [Select]

Application: Couatl64_MSFS.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an internal error in the .NET Runtime at IP 00007FFA1963657C (00007FFA19630000) with exit code 80131506.

I am receiving this same error/issue, shortly after taking off. Seems to be occuring ever since updating to 3.7.5 GSX PRO.
