M.2 SSD issues once installed into ps5

[Who Dares Wins]

So i went a bought a WD Black SN850 1TB M.2 PCIe 4.0 NVMe SSD/Solid State Drive with Heatsink and placed this in my ps5, transferred all games etc and was working fine and still is but when i place the ps5 into rest mode the computer shuts down completely anyone else having the same issues and if so how did you sort this out
