If you have a SDCard inserted in your Book 4 Edge Snapdragon windows - eject it and reboot the machine - afterwards it starts to work properly.. then you can reinsert the SDCard (I was using a Samsung 512GB EVO)

Sometimes, hardware components can be disabled in the BIOS. Enter the BIOS during startup and verify that all relevant devices are enabled.
