We see this error on a Windows 11 Enterprise Multisession server when we close Adobe Acrobat Reader with a loaded document.
Our system is fully patched, 23h2 with latest monthly updates.
We started to get this monday 15 of April and 14 of April these updates were installed:
2024-04 Cumulative update for Windows 11 Version 23H2 for x642024-04 Cumulative update for .NET Framework 3.5 and 4.8.1 for Windows 11, version 23H2 for x64
Probably the cause of an update.
What I did so far:
I started reinstalling Adobe which didn't help.
I run some system checks like sfc /scannow and dism /restorehealth which didn't help.
Sometimes it looks like it's away but later it starts to show up again.
chkdsk didn't found anything.
No logs to be found in Eventlog about this.
System reboot.
This turned out to be an Adobe bug and is not because of any Windows update. I just wanted to clarify that.
