2. This morning, Windows installed a major update (including firmware). My system is now running on Windows 11 Pro, Version 25H2, OS build 26200.7840 and has Windows Feature Experience Pack 1000.26100.291.0. When I tried to open InDesign, it wouldn't open. I followed the instructions from this post (https://community.adobe.com/questions-671/indesign-v21-not-starting-after-update-win-11-897997) and uninstalled all of my Microsoft Visual C Redistributable Packages and reinstalled them from the link posted by Anubhav M 3 months ago.

That (seemingly) solved the problem, but when I opened an existing InDesign file, I got an error message telling me that all of my fonts were missing. It listed the missing font as Calibri (OTF). I updated the font to the version of Calibri that was extant on my computer, and that seemed to solve the missing fonts problem.

However, I just tried exporting my InDesign file to a PDF, and in Background Tasks it has been stuck on Adding Font--trying to add Calibri Italic, Calibri Bold and Calibri Regular for at least 45 minutes now. The Export to PDF function is queued behind the adding font function, so essentially I am unable to export a PDF.

1. I expected that when I opened an InDesign document that was working last Friday, I would not receive a missing font message. And once I received a missing font message and changed fonts, I expected that the program would be able to create a PDF as usual.

2. See above

3. I have attached a screenshot of the background tasks window. I can upload a copy of the file if you would like to troubleshoot it.
