Hello,
I check this update history information, not find related known issue about not mount SSD.
Check if the SSD could be found in device management. Go to the Device Manager, expand Disk drives, identify your drive.Also I suggest that update SSD Firmware:. SSD’s Firmware aids the SSD to communicate with the operating system. If it’s outdated, you might encounter issues.
