Preview thumbnails not displaying in Finder (Monterey 12.7.4)

• Safe mode doesn’t solve the issue either.
• The search on Activity Monitor for "com.apple.quicklook.ThumbnailsAgent", force quit, and relaunching the Finder works momentarily.
• Any new file I create after that, it goes back to the icon file but not the preview thumbnail. I work creating school material, so that preview is very useful to me.

Does anyone know of a permanent solution for this? It's pretty annoying having to do the activity monitor thing 10+ times a day, specially when the relaunching won't re-open the Finder windows I had to relaunch. Then, I have to open them again manually.

I have read the following in some forum, but I've not tried it yet, anyone knows if it will help as a permanent solution if none other is out there:

----------

Dock this script created in Automator and saved as an App and you can even set a short cut if you will:

Code:

do shell script "launchctl kickstart -k gui/501/com.apple.quicklook.ThumbnailsAgent" user name "YUOURUSERNAME" password "YOURADMINPASSWORD" with administrator privileges

do shell script "killall Finder"

------------

Any tip, help, and specially a solution will be appreciated.

Thanks.
