I was reminded again after doing a backup restore that Vegas becomes crash-happy if "GPU Acceleration of Video Processing" is turned on. It should probably be turned off by default, Magix.

Mine is an i5 8xxx with Intel HD Graphics. I suspect many are plagued by this issue, as well as many identified video cards from various (2) manufacturers.

A highly detailed article was written by @Nick Hope here:

NOTE that turning this feature off does not turn off GPU processing of render.
