I've got an external SD card reader connected to my 2020 MacBook Air M1 via USBC. The drive shows up on Disk Utility but it fails to mount the SD Card in the reader. Using the same SD Card reader in an identical MacBook Air running Monterey it mounts it without an issue.

Any ideas how to enable macOS to read from the device?
