Problem rendering in Windows Version

Greetings.

I'm a new user of Premiere Rush. I created a simple 30-second video to make sure everything was copacetic, then spend days building a larger video. While the short video rendered fine, the more complex one creates a glitched result every time. I don't get any errors, but the video gets glitched and drops whole sections. Sometimes seconds, sometimes minutes. I did see one specific clip that seemed to always glitch but removing the clip didn't help the rest of the video. Changing the resolution doesn't help, and there really aren't any other settings.

My video drivers are all up to date, as is the software.

Any suggestions, or am I just screwed?

Thanks in advance.
