InDesign files corrupted and unable to save after Windows 11 update KB5074109 (January 2026)

I have the same issue with InDesign 21.2 and 20.5. running on Windows 11.  I cannot do anything useful with InDesign at present.

I had the samen problem. SOLVED NOW by checking my computer for the latest update of Windows. 

Turns out thwe software 2026-01 Update (KB5078127) (26100.7628) has solved it for me.

Good luck!

Hi everyone, I uninstalled KB5074109.

Now my computer asks me every day to install it again, so I’d like to understand when it will be safe to reinstall this update.

Does anyone have an answer?

Thank you

There's a new Windows update today! It's working and saving now!

Yes, I've had the same problems.

It happens also even when just saving a document. It's maddening. Even just clicking in a space without making any changes whatsoever causes the doc to show that it's insaved.

I can't even add chapters to a a book without the program crashing.

================

I followed the recommendation to removed the Win11 KB update, and that seems to have "fixed" the problem.

I've been able to accomplish the tasks mentioned above without any problem so far.

Makes me want to bun an Apple system.

I am also experiencing this issue. InDesign files, old and new, are becoming corrupted and unable to be saved.

These glitches have been plaguing me since the last InDesign build (21.1), which predates the Windows update blamed for this. I did a complete uninstall of all Creative Cloud apps and the CC software, did the Adobe clean, and then reinstalled CC and InDesign. Currently, I have been able to open the files that were corrupted by the current glitches - some can be 'fixed' and saved, some not. However, I have not had any issues creating and saving new InDesign files. This is without removing any Windows security updates.

I've been attempting to create files for various things that I have usually never had issues with. They all have similar elements, but are nothing resource heavy. Mostly test with logos and design elements. It works fine until I try to save. The save then results in an error/failure. The error changes nearly every time. Shortly after the error, InDesign crashes. Occassionally it does give me an option to repair the file and save. I've even started file from scratch and rebuilt everything I need in the document, but then saving results in a similar error. I reinstalled InDesign completely and it still fails at saving. I am running InDesign 2026 v21.1 x64.
I also have co-workers having similar issues with errors varying but similar error messages.
Here is the crash report I was about to capture and I included the popups from the errors:
