The File History log still has problems after the KB5126657 update.

This sounds like a possible File History issue after the KB5126657 update, especially since backups complete but timestamps and previous versions aren't updating correctly.

Try these steps

Check the backup: Open Control Panel → File History and verify the correct D: drive is selected.

Restart File History: Turn it off, restart your PC, then turn it back on.

Test with a file: Edit and save a small test document in a folder included in File History, then run Run now.

Check Previous Versions: Right-click the file → Properties → Previous Versions. Remember that this works only if a previous version was actually backed up.

Protect your existing backups: Don't delete the File History folder or format the D: drive while troubleshooting.

If the error “Element not found” persists, report it through the Windows Feedback Hub and include the KB5126657 update number.

Important: Keep a separate copy of your important files until File History is working reliably again.
