Quick Preview not working on Mac OS Monterey

Understand, we are all working Remotely from all around the world. Therefore, we do not have the On-Hands experience the User ( you ) has with this computer.

The next best thing for us to having an actual On-Hand experience on this computer is to follow the steps below

But that has already been suggested.

Download the Application Etrecheck directly from a well Respected ASC Contributor. And Safe to use.

The application is free or paid from added features. 

Run the application with Full Disc Access ( Security & Privacy - Full Disc Access ).

It will take a Snap Shot -  both the hardware and software.

 The Report will Not Reveal Any Personal Information. 

Post back the Full Report - copy and paste - using the Additional Text Icon ( 3rd Icon to last )

We can have a look at the report for possible issues and may have possible suggestions to resolve the issues.

FWIW, few people have the issue, I certainly haven't on Intel or M1 Macs running Monterey. Normally booting in Safe Mode, then restarting normally resolves the issue for those that reported the problem.

Install EtreCheck and post the report. Allow Full Disk Access.

Use the Additional Text icon to paste in the report.

To add to the already suggestion above.

Is user profile accurate MacBook Pro 16″, macOS 12.3 ?

If Yes, perhaps the computer is missing Monterey 12.4 released May 16, 2022

Quick fix, see: https://www.reddit.com/r/MacOS/comments/qguni0/quicklook_preview_with_spacebar_not_working_macos/

"Option + Secondary Click (right click) on Finder in the Dock then click Relaunch."
