Tyler, don't spend a ton of time on this. I'm going to recreate it one step at a time to see if I can find where the problem might be. I'm guessing it's inexperience and changing so many things during the process. If it continues, I'll ask for help again.
Beginners' Questions Can't open PDF's after saving
Inkscape.org
I saved a file as PDF 1.5. Received an error that Adobe could not open it. Saved it again as 1.4 and it opened fine.
Today, saved a different file and it wouldn't open either way.
What causes this? Any tips for helping resolve?
Describe your OS & version, the version of Inkscape and the installer you used, plus any special hardware like tablet/stylus or multiple monitors.
Windows 10 Pro Version 1909, Inkscape 1.02 inkscape-1.0.2-x64, no special hardware
The last file I tried has 1 imported png file, nothing else created outside of Inkscape
I tried removing the png, no change. I also tried saving as a plain svg.

Inkscape 1.0.2 is saving invalid font names to PDF files. You could save text as curves or downgrade to Inkscape 1.0.1.

It only does it sometimes. I was able to recreate 3/4 of my document before it wouldn't open as a PDF. Thank you Aero for the suggestion.
