macOS Monterey QuickLook Bug

 There is a bug with QuickLook on Monterey. QuickLook works by selecting a file and hitting Spacebar, which opens a previewn of the file so you can have a look at it right  in the Finder. Very useful to quickly scan through documents, videos etc.

On Monterey though, QuikLook can go bezark and instead of opening a preview version of the file, it just opens a dumb window with a small thumbnail and generic file info.

If this happens, open Activity Monitor, Search for "QuickLook", select all that apply. Example: QuickLookUIService (Finder), QuickLookUIService (Quicktime), QuickLookSatellite, quicklook, com.apple.quicklook.ThumbnailAgent, etc. With these selected, click on the Stop button to stop the selected processes.

Re-launching the Finder seems to be working as well for some users.

QuickLook should work fine again. Until next time... Repeat this workaround while Apple is working an a fix.
