I play Arma Reforger through GeForce NOW Ultimate via Steam.

When I join the modded multiplayer server "Conflict in Europe", I can enter the server and play normally for some time. The crash does not happen during mod downloading. It happens later during gameplay, usually after around 1 hour.

GeForce NOW then crashes/shuts down the session with error code 0x8004000B.

This started after the latest major Arma Reforger update. Before that update, I was able to play on the same modded servers through GeForce NOW without this issue.

I also tried another modded multiplayer server, and the situation was similar - after some time of gameplay, the session crashed with the same error.

Steps to reproduce:

1. Launch Arma Reforger on GeForce NOW Ultimate via Steam.

2. Open Multiplayer.

3. Join the server "Conflict in Europe".

4. After around 30 min/1 hour of gameplay, the game/session crashes with GeForce NOW error code 0x8004000B.
