System Fond StixSize not working correctly

[defaultsadkc11g4yrf]

Hello together,
for our projects we use for math formulas the system fond Stix. It is a huge font-family that also has the font called StixSizeSym in regular and bold. In the newest InDesign Version 17.2.1 the regular type is not working anymore. It shows that the font is missing. 
I've tried deinstalling InDesign and installing it again without any presets but it didnt work ether. I checked older Versions like Indesign 2021 and there it is working. So i deinstalled Indesign Version 17.2.1 again and installed Version 17.0. In 17.0 it seems to work. Do you have any guesses what the problem could be? Or is it a bug? I'm afraid that i have the problem in futur in newer versions aswell.

Thank you in advance!

Use it old version! Just don't forget to talk with Adobe Support Chat about it and add bug on indesign.uservoice.com

And maybe in a galaxy far far away their conscience torment them and Adobe will add formula-redactor inside InDesign.

Have you tried it in the private InDesign/Fonts folder? Have you tried it in a document fonts folder?
