I recently bought a second M.2 SSD, an Acer Predator GM7000 1TB NVMe Gen4. I installed it in the second M.2 slot and my computer won't detect it. It doesn't show up in the BIOS or Disk Management. I have the latest BIOS version (P8.01) and fully updated drivers. Please help.

Specs:
B450M Pro4 motherboard
SABRENT 1TB Rocket NVMe PCIe M.2 2280 (current SSD)
Ryzen 5 3600
Nvidia 2060 Super
32gb 2133MHz Ram
Windows 11
