Unknown Error in Word Output
I'm getting an unknown error in Word and haven't been able to pinpoint the cause. I get this when I try to open the Word output:

My other projects are fine, just this one. Also, the HTML output is fine (I checked each page). I did some testing by changing the CSS with a project that works, removing the link to a template (same template as the working projects), and adding individual topics to a test TOC. This last test with the TOC showed some success. A topic without a variable was successful. However, removing variables from other topics that failed previously was randomly successful.
I'm using 2020.5.71. When I checked for updates, I got 2020.5.0, which I did not install.
