You were right - updating the drivers did fix the issue, apparently geforce experience did not update them automatically when I thought it did. Thanks for the help!

When I updated my driver it still has the same problem. I checked it many times.

the 940m is at BEST inconsistent about nvenc support, and more commonly outright doesn't support it.

Any news for 940m?

Is there any problem with the NVidia GeForce 940MX (as it is not the 940M) because it is not working for me with the same error log just other cpu (namely 7200U but that shouldn't be the problem)

(edit: The thing with the CPU)
