PDFs not opening on new macbook air

Hi there,

I got a new MacBook Air recently, and find that I can't open PDFs. I have had a look in launchpad, and I do have Adobe Reader in there. I also tried re-downloading it in case there was some problem, but that didn't seem to make any difference.

When I click on a PDF, nothing at all happens. If I click on the Adobe icon in the dock, nothing happens. It's not bouncing and it doesn't say 'not responding' if I click on it.

The only things I've done since I got it are migrate everything over from my old MacBook, and update the OS to Monterey.

Any ideas???

Many thanks in advance!
