Session.xml emptied with Windows upgrade while PC left in Sleep mode with Notepad++ open

[mpopejoy-dxc]

Description of the Issue

"Lost" my session during Windows updates that occurred when I left my PC in Sleep mode with Notepad++ (and other apps) open.

Steps to Reproduce the Issue

1. Notepad++ open with dozens of open files (other apps also left open)
2. Windows -> Power -> Power -> Sleep
3. (me -> bed -> sleep)
4. (some hours later) Windows installed 2022-10 Cumulative Update for Windows 10 Version 21H2 for x64-based Systems (KB5018410)
5. Powered on/woke up PC

Expected Behavior

(Before knowing that a Windows update had occurred, I expected...) all apps and windows to be open and on the monitor (of 3) that I left them on - including Notepad++ with all the files I had open.
(Since a Windows update did occur, I'd expect...) have to log in to a fresh Windows session and potentially get a complaint from some Office apps that I hadn't saved or shut down properly. Upon opening Notepad++, I'd expect all the files I had open to be open.

Actual Behavior

Windows re-logged me in and reopened all the windows and apps I had opened (Firefox - 2 windows, multiple tabs in main one, Chrome, Outlook - 3 folders and an open popped-out message, Teams, etc.)
Don't remember if Notepad++ was open with just new1 file or if it wasn't open so I launched it, then seeing only new1 file.

Debug Information

Notepad++ v8.4.6 (64-bit)
Build time : Sep 25 2022 - 19:51:39
Path : C:<maskedFolderName>\Notepad++\notepad++.exe
Command Line : "C:<maskedFolderName>\Notepad++\change.log"
Admin mode : OFF
Local Conf mode : ON
Cloud Config : C:\Users<maskedUsername>\Dropbox
OS Name : Windows 10 Enterprise (64-bit)
OS Version : 21H2
OS Build : 19044.2130
Current ANSI codepage : 1252
Plugins :
mimeTools (2.8)
NppConverter (4.4)
NppExport (0.4)

Note: one posting I found indicated that reinstalling N++, but not deinstalling, solved their issue. Even though I didn't expect it to help, I tried that. That was before capturing the debug info above.

I found nppLogNulContentCorruptionIssue.log in Cloud Config folder with timestamp of Windows upgrade so I know what time session.xml was overwritten with 193 bytes instead of the previous 374907. File attached.
nppLogNulContentCorruptionIssue.log

Thanks for the log and sorry for the session lost.
Probably the same as the #9850 .
