Fix the igd12um64xeh.dll

[Simski]

I play Microsoft Flight Simulator and Microsoft Flight Simulator 2024. For both games, I use an addon called GSX Pro, which gives me pushback functionality for aircraft and other things.

This addon connects to the simulator through an external scripting engine program called 'couatl64' with different versions for each simulator, but which have the same principle. This program is having problems on my PC.

Recently, the developer released an update to this program, and after that, I started having problems with it. Basically, when I try to use it within the game, the program crashes and restarts automatically, only to crash again and so on, continuing this cycle of crashes and restarts indefinitely. It's important to note that the crashes are limited to the addon only and do not affect the game itself, which continues to work normally.

The program log gives no clues as to what is causing this. So I checked the Windows Event Viewer and it shows that the faulty module that is possibly causing these crashes is igd12um64xeh.dll

I did some research and found that this dll is possibly related to the Intel Graphics Driver. I brought my findings to the addon developer and he has no idea what is causing this. It just raises my same suspicion that some modification of the program made it somehow incompatible with Intel Arc cards.

I know it will be very difficult to investigate a problem with a third-party add-on for a game rather than the game itself, but I am willing to help you with whatever is necessary.

My card is an Intel Arc A770 16GB and I'm using the latest drivers.

update on this?

I have the same issue with my sparkle B580 graphics card and the GSX add on for both Microsoft Flight Simulator 2020 and 2024.  No issues with GSX on my pc with the Nvidia MSI 3060 graphics card.

I am also experiencing this error using GSX.
