M1 MacBook not mounting any external disks automatically

My new M1 MacBook will not automatically mount any external storage media. I've tried SD cards, SSDs, and other external hard disk drives with the same conclusion. Each time, I need to go to Disk Utility and mount the drive manually. Ironically, they all work well on my other Macs running macOS Big Sur and other OS versions. How can I set the drives to automount on Mac? Those drives are from my clients, so I can't reformat them. Any suggestion?

The drives seem to be fine, as they mount correctly on your other Macs. So, I suspect the issue is with your M1 MacBook, likely due to third-party software intervention or software bugs.

I suggest you uninstall any security software, antivirus, or VPN installed on your Mac, then try one of the offending drives again.

If it doesn't work or you don't have such software installed, upgrade macOS Big Sur to the latest macOS compatible with your M1 Mac. The software upgrade can update disk drivers, install bug fixes, and apply security patches.
