SN550 Not detected on Asrock X300

SN550 Not detected on Asrock X300 Mini PC.
Sata SSD detects fine, but SN550 in either m2 slot works sometime and the detection drops out causing return to Bios. Any help would be appreciated.
I have two of these SN550s that exhibit same behaviour.
Have updated SSDs to latest firmware with same result

I have the same issue with an Asus Z270 Prime A, the firmware update doesn’t fix my problem, please WD help us!

I might as well comment here as well. Experiencing similar issues with same drive. WD, please fix it for us.
