Excel .xlsm files showing “We found a problem with some content” after saving

Hi everyone,

Good day.

I’m currently experiencing an issue with Microsoft Excel involving macro-enabled files (.xlsm) that contain VBA code and are stored in Microsoft OneDrive.

Scenario:

• I open an .xlsm file (with VBA), make edits or even just open and save it.
• When I reopen the same file, I get the error:“We found a problem with some content… Do you want us to try to recover as much as we can?”

Additional details:

• This issue started happening on April 15, 2026.
• Files created in 2023 were working before, but now they are no longer working even if I did not make any changes.
• The issue now happens consistently even without modifying the file.

What I’ve tried:

• Opening and repairing the file
• Saving as a new file
• Checking OneDrive sync

Has anyone encountered this issue recently, especially with OneDrive syncing and .xlsm files? Any suggestions or fixes would be greatly appreciated.

Thank you in advance for your help.
