OS Build 26200.8894 Office Errors - Major Headache

My system PC:

Windows 11 Pro 25H2 x64 bit OS with OS Build 26200.8894

Most recent update: 7/19/2026 update (KB5121767)(26200.8894)

AMD Ryzen 5800X 8-core (3.8 GHz), 32 GB RAM

Graphics NVIDIA  G Force GT 710 (2 GB), 3.24 TB used of 7.28TB storage

As a result of the most recent update I am unable to open Word, Excel, Photos, and pdf files. Any new docs I create will open properly but the files previous to the update will not. I also tried using my backed up files, copies on a thumb drive, but I am told they too are corrupted. All of these files worked before the update.  

For the Word files I get an error “Word found unreadable content is xxx.docx file," then it asks if I want to recover it and I click YES but I receive another error telling me to use the text recovery converter.

I have searched for this program but have been unable to locate it. I used the directions posted online but my system path is not the same as described. I get similar results with the photos and Excel programs. Even if I do locate and correct this document with the text recovery converter program, does this mean I will have to do it with every document, spreadsheet, photo, and pdf I own?

This has happened with past updates but was self-correcting after a subsequent update but this one has not and it has been nearly a week.

Any ideas how I can fix this major headache?

Windows for home | Windows 11 | Windows update

    I just tried to repair Office again. That didn't work so I did the online repair and that also did not fix the problem.

    Office Professional Plus '21

    Yes, I tried multiple times to repair office and it didn't work. I will try it again.

    I know it must be an Office issue but I believe this last update was for Win 11 or was it?
