ProMaster External Card Reader

My external card reader (ProMaster 6 in 1 USB) is not recognized by my MacBook Pro since I installed Mojave. It worked with High Sierra only a few months ago, so I know it's not the card reader or the card.

Why is my SD card reader is not showing up in Disk Utility? I am new to the MacBook world, with the MacBook Air with M1 chip. I've purchased the USB adapter from Apple. when I plug in the card & card reader to the MacBook it does not recognised it being there, so I cannot format the disk to be able to return it to my cars dash-cam. Can anyone offer any advice please?

It could still be the card reader or the card but try resetting the SMC.
