Using the search in the taskbar, start or filexplorer doesn't work.
Task manager shows SearchHost.exe starting up when trying to search but then quickly gets suspended.
I've tried safe boot, scannrow, troubleshoot, resetting cortana, updating and basically everything suggested to other users.
When I upgraded to windows 11 last night the search function was working until today. I've changed the font yesterday but then later reset it back to normal using control panel and the registry but to no avail.
