I also have the same problem with Windows 11, 24H2, Nvidia graphics 1070Ti, MSFS 2020. All the suggestions listed here did not work for me except killing the task and running the kill task batch file. I even uninstalled ALL Nvidia apps and drivers and did a fresh install of an older Nvidia driver V 566.36 which many believe to be a stable driver. Still same problem. No problem with MSFS 2024.
