Sandisk ultraflat usb 3.0 not working on MacAir

I recently updated my Mac to Monterey 12.4 and now I am unable to access my usb. Mac is not picking up the usb at all. I’ve tried restarting the computer and made sure all of the settings are done correctly but still nothing. Does anybody have helpful advice? Thanks in advance.

I would recommend you contact the place where you got your Mac upgraded or to the source of the upgrade. The flash drive didn’t change, your equipment did. Probably some new security feature.
