Bug: Adobe Fonts are corrupting when using the Acrobat accessibility tools.

I am making interactive PDFs from an InDesign document and Adobe Fonts corrupt upon opening in Acrobat, but just for the accessible features. (e.g., screeenreaders). I have tried clearing the cache, re-installing apps, Adobe customer support reps, etc and no one can fix the issue. I suspect it is due to licensing restrictions on editing font files - something is sending the signal that the Adobe Font is being edited when Accessibility Tools are used in Acrobat, but this should be allowed when the intention is to make the document accessible.

1. Adobe InDesign 19.5.4 (also tried previous versions such as 20.4.1)
2. Use Acumin Variable Pro font from Adobe in InDesign, make the document interactive (basic text form fields suffice to replicate the error), export as interactive PDF, open in Acrobat, open a screenreader and hear the corruption or open Accessibility Tools and tag the text (on a non-interactive part) and then see the text is missing letters and there are periods where spaces should be. Also, Acrobat crashes half the time during this process.
3. Expected result - that Adobe Fonts work as other fonts in this scenario and that exports PDFs using Adobe Fonts can be edited for accessibility without issue.
4. Crashed app, incomplete work, and failed accessible document.
5. Can provide test file if you contact me privately (adobe).
