SD card doesnt work in Lockdown mode on Ventura

I plug my SD card into the SD card slot on my MacBook Pro (2022, M1 Max). The system asks if I want to connect the device. But my permission doesn't work. The SD card doesn't show up on my MBP. The setting of "Allow accessories to connect" is grayed out. I've enabled Lockdown mode. Whether it is related to this?

You barely need to reset the security settings to make your SD card show up on your Mac again.
