Hello ​@Gweeeen ​@JuJuFri

Hi Gwen,

Many Windows 10/11 users have been suffering from file corruption problems owing to a faulty Windows Update patch in January 2026. Maybe this is your situation too?

Many of these Windows users are also OneDrive users, too. Is that the case with you?

You might try patching forward to the latest Microsoft Windows Update (KB5074105 or newer, such as (KB5077181). I would try this solution first.

Others say to roll back the update (KB5074109) that appears to be causing this in the first place.

This is a Microsoft Windows Update problem.
