SD Card Reader Not Working

I recently updated to Monterey 12.6.2 from 12.6.1. After the update, the SD Card Reader no longer works. Worked fine up thru 12.6.1. Have tried multiple SD cards and none will work. Tested the same cards in an external reader via USB 2.0 All test cards mounted and worked correctly in the external reader. The Mini had successfully read all the test cards via the onboard SD Card Reader before the update.

Followed suggestions to "clean" the slot with a non-metal toothpick and used compressed air to blow out the slot. Neither helped. Found a suggestion to restart the USB daemon via Terminal. Did not work.

I've seen this problem discussed about 12.6.1, never on 12.6.2. The solution to fixing on 12.6.1 was to update to 12.6.2. That's when mine stopped working.

Any help would be appreciated.
