I have the same issue, but not for "long" or short sleep. It started with the Windows 11 upgrade that now when my computer goes into sleep mode (for any duration), anything open in applications like Edge, Outlook and Word are closed, and then generate messages such as "Windows did not shut down normally. . .".
In Word, it generates a recovered unsaved file that I then must sort out saving and replacing the original file. This can happen over short periods of time of walking away from my desk, etc. I have pretty good file saving habits. This is both new and very annoying. Is there a fix?
