Hello! Safari (14.1) suddenly stopped displaying PDFs on my iMac Pro 2017 (MacOS X Big Sur 11.3.1). For instance, when I click on a PDF online, it displays only a blank window or placeholder. If I try to download the PDF, there is only a blank file. I have also Adobe Acrobat Reader DC (2021.001.20155) installed. What could be happening? Thank you!

It also does a basic check of your startup disk, similar to using First Aid in Disk Utility.
And it deletes some system caches, including font caches and
the kernel cache, which are automatically created again as needed.

Thank you very much! Before doing the full procedure you suggested, I've first deleted Safari's cache. It worked!
