Can't use Source Han Serif in Acrobat! (but can in other Adobe apps)

I installed the Source Han Serif Simplified Chinese font from Adobe. However, when I try to use this font in the header or footer of a document in Acrobat, the text simply disappears. I can use other Chinese fonts (such as the OS included Songti) but not Source Han Serif. Funny enough, I can use Source Han Serif in other Adobe apps (such as Illustrator). But in Acrobat it gives me trouble.

I have already tried reinstalling the font (reactiving it in the Adobe CC app) as well as reinstalling Acrobat to no avail. I also tried downloading the font directly from Github, and also installing the Google variant (Noto

Serif SC).

I also tried this on 3 different computers - including 2 Macs (running 13.1) and 1 Windows 11 PC

I still think this issue is related to the font somehow being improperly installed. Any ideas? Thanks!
