I just updated to Win11 on one of my PCs. Only on this PC, the taskbar "search" magnifying glass doesn't pull up the search box (it turns colors to indicate it's active but no search window appears) and if I click the Windows taskbar icon and start typing, or click in the search field in that popup window, the popup just disappears and doesn't bring up the search box.
On my other Windows machine everything is fine. What did I do wrong & how can I fix it? (Yes, I've restarted, updated to latest, and restarted Windows search service).
I do notice the Windows Search Indexer taking a fair amount of CPU and I/O. I checked the administrative logs, don't see anything interesting.
