Latex fonts missing in Illustrator Windows

Hi everyone and thanks in advance for your help.

I am using latex fonts to generate graphs on Python. I wanted to modify and arrange the graphs in a figure using Illustrator 2023. When I open the pdf of the graph I want to modify on Illustrator, it tells me that font CMSS17* and a bunch of other fonts are missing. I know for a fact that the fonts (*.pbf and *.pfm formats) are installed in C:/Windows/fonts for all users. I also checked for these fonts on the creative cloud font manager and they are not available there.

I followed this tutorial up to step 4 where the C:\Program Files (x86)\Common Files\Adobe\Fonts doesn't show up on my computer, which leads me to think that it might be an issue with the Illustrator version (2023).

Please help!
