Hi,
Since your Windows is not installed on the SSD, you can uninstall the SSD in Device Manager (devmgmt.msc), then reboot the computer to see if the SSD can be correctly identified.
If the issue persists, try connecting the SSD to another SATA port on your motherboard. Also make sure the SSD can be recognized correctly in the BIOS / UEFI.
Best Regards,
