RaceRender crashing often when creating videos.

I apologize in advance as I don't have any specific crash reports to relay since I never see them and don't know where they are stored. All I can say is that I have been creating videos with the "internet / upload Full High-Def (1080p)" profile, unmodified. My source content is in 1080p and comes from my GoPro Hero 8 black. I got most of my projects to successfully output a video by selecting the multitask option while it is rendering, because the Maximum option almost always crashed it in the first several minutes of rendering. I was okay with this solution but now I have a project that is a little longer, 2hrs as opposed to 1.5, and even having multitask selected, I can't render the video before it crashes and then I need to start over.

I am using Windows 10 64bit, and using RaceRender 3.7.3 Ultimate 64bit.

I would appreciate anyone's help.
