NVMe Base not found

Hi there,

after trying to setup the NVMe Base i am not sure why it does not show up.
I checked the ribbon cable. The disk is working on other pc.
I used different images and OS. However the issue is the same:

I am using thee 27W official PSU and Transcend 1TB TS1TMTS425S NVME

I bought it in december using presales but never used until now. Any ideas ?
