i am having the same problem.
ZERO problem on my 2019 laptop with windows 10 and 20204 version of office.
new files, files with text (no formatting), etc. all of them become corrupted and unrecoverable as soon as i password protect them.

I had the same problem occur at the same time on a Dell laptop with Windows 11, and also on an HP decktop using Windows 10. Both are on the same network. All pwd excel files got corrupted.
Before you start save a working copy of your spreadsheet without the pwd on a flash drive, and also keep one on your laptop.
I found the solution and all is fine as it was before. Here is what I did:
Control Panel > program and features > select Office 365 > change > online repair.
It took about 5 minutes on the windows 11 laptop, and about 30 minutes or more on the Windows 10 PC.
Create a test spreadsheet and save. Open it again and put a pwd on it, save and close. When you open it again it should be fine. At least mine was. Then you can open the former corrupted spreadsheet and and add a pwd. Hope it works. Let me know. Good luck.
