Mac does not recognize SanDisk ExtremePLUS SD card

Hello all,
my Mac (macOS Monterey) does not recognize my SanDisk ExtremePLUS 150MB/s 64GB SDXC.

I use a card reader. Is the problem with the SD card reader or with my Mac?

Strangely, my other SD card SanDisk Ultra 40MB/s 32GV SDHC is recognized. Do I need a special SD card reader for the SDXC cards?
