SD card slot on iMac

I upgraded to Monterery OS yesterday and shut down after installation. I re-opened the iMac this morning to discover that the SD card slot does not work. I also tried my husband's Apple USB C to SD card reader but that wouldn't work either. I checked various SD cards to make sure none were faulty and the result was still the same: no card opened. Any ideas how to solve this one please?

Known issue with Monterey 12.0. If you have 12.3.1 then do a SNC and Nvram reset
