This can have something to do with the nview application that comes with Nview-driver installed on your pc (especially if Altium starts intermittently.) Please check if the Nview Desktop Manager installed on your pc.
If so, please go to this website: https://www.nvidia.com/en-us/design-visualization/software/quadro-view/release-highlights/ and update the nview software.
An alternate approach, if you don't really use the Nview Desktop Manager, would be to uninstall (or at least disable) this software. There is no impact on the installed Nvidia-driver.
