Thanks for the information. This helps. And please don't worry about the hurry — when problems crop up, it's sometimes challenging to look back at the details when the alarms go off.
For what it's worth, I'm running much the same configuration as you — I haven't updated to IDCC2026 yet, but otherwise I'm running much the same configuration as you on the latest model Mac Mini. I am also running a later version of the RightFont app — v.9.7. But I'm pretty much equipped as you are.
Since the the main thing that's changed is installing a few fonts into your font manager, perhaps the first thing to try is turning off RightFont, then trying to open IDCC2025 if you still have it installed:
1) Restart the system
2) Quit RightFont
3) Then try to start InDesign
It may or may not fix the issue, but we can at least eliminate the variable. There's also an incremental update to InDesign CC 2025, v.20.5.1, that you may want to try next.
I'll confess that I'm making guesses here, because I haven't heard of anyone having the issues you're experiencing. That's not to deny the problems you're obviously having, because you wouldn't have asked for help here if you weren't having them. But it's rather atypical, so perhaps the best, and simplest way to start is with the basics.
I hope this helps. But if it doesn't, feel free to come back here and sound the alarm. We can try and help you through this and get you up and running the way you expect. There are lots of sharp people around here who may be able to lend a hand.

Ok, it wasn't RightFont. It was something with the Indesign cache and/or preferences. I deleted the cache and reset the preferences. Now the program is working again. But thank you for your time.
