I have had the same issue....., The support from Intuit told me that I have to update Microsoft 24H2 to the new Oct 24 updates - this update caused endless problems.  Many people have had issues with updates causing internet, gaming, and other hiccups.  I ended up spending 36 with 8 Microsoft chat supports; each one started from restore, and each restart takes you to the new person, then here we go again, a circular motion.  Update stuck at 14% then again on 46% hours on end.

I finally got elevated to a tech guy who did not ghost on me when I said update issues with 24H2, he said that my C drive operation system D... folder something (can't remember)  was 100% full so it would not allow any program updates.  It has over 700k files from all the calls, and nobody cleaned it up.  Surprisingly one drive also used a lot of memory.  The cleanup took another 2 hours, and the update still stuck at 46%, so I reached back again to chat, this one started to restore even after I said "Please do not recreate the restore point and restart, I have had 7 so far the program is clean,,,," so I close the chat.  It's Xmas eve and I was ready to buy a new PC from Costco,  Just wanted to give it the shot at the last minute, this time my Proseries went through.

I feel that Proseries's error message was wrong, the support should not recommend us to update 24H2 - A Big no no....  I was forced to pay upgrade for hotmail even though my Outlook has plenty of storage left.  I was going to upgrade like you did because mine was 2019 student, but it was not necessary in the end. 

My thought after 36 hours with Microsoft chat service is that perhaps Microsoft updates clocked in so many files that we never dare to clean up without guidance from tech support,  This over the years is blocking the C drive, it looks like Proseries is reading the old updates info (Microsoft 10 -2016 for mine) but not the new updates in our system (we both have Microsoft 11).  I don't know why but installing 24H2 updates get you nowhere.  Proseries also gave me a few more error messages like Quickbook and/or Proseries 23 is on,- but it's not.  However,  it is doing something in the task manager; so I have to go to task manager to disable the app, I am blocking all Microsoft updates from now on until the end of the season.

So mine is fixed on Xmas even at 6 pm - for now.... I hope Proseries is not going to give us any more trouble with future updates.

Wish you luck.
