"PCIe 4 Ready" - MSI B550-A Pro M.2 Slot Not Working

Brought to you by MSI! Not my usual type of content, but I haven&really been able to make videos because my new PC will not POST with a drive in the M.2 slot closest to the CPU. I&tried two different drives, one of which is confirmed to be supported by MSI. The two drives are the Sabrent Rocket Q4 and the WD black SN850, which are both PCIe Gen4. Kind of out of options so hoping someone here will be able to help!
