Closing Task Manger always resets App History to zero for all apps

I am using Windows 11 Pro Version 24H2 (Build 26200.4188) on a NUC 12 model NUC12WSHi7. Recently when I tried to check App history in Task Manager it showed 0 and started accumulating time although it was set for history from two weeks prior. I have looked through settings for some control of this. The only control is turned on and I am signed in as Administrator. Leaving Task Manager running in background allows it to keep history going. Closing it stops the history and resets all to zero when I restart it.
Clicking on Settings in App History in Task Manager Shows "Show history for all processes" is checked.
Is there somewhere else that is stopping App History?
Thanks for any help,
Frank

I’d have assumed this would of been fixed by now but apparently the Windows 11 24H2 Task Manager displays a zero count for apps, background processes, and Windows processes when the "Group by Type" view is enabled after installing the October 2024 preview update (KB5044384). This is a known issue that Microsoft was investigating and working on a fix for. While the Task Manager incorrectly reports zero processes, the actual apps and processes are still running.

Thanks antspants. I assumed something like that had happened. I'll just wait and see.

Since October last year though. Rumour has it, Microsoft has a team of developers (All on holidays?)
