I'll cut to the chase,

I've got a new SSD that's faster (gen 4 instead of gen3) and larger (2TB instead of 1TB)

My motherboard is not detecting either SSD card in the second M2 slot. (according to the visualization and list in the BIOS)
The first M2 slot detects both SSD cards, so the cards aren't faulty.

Windows Disk Management doesn't detect the Disk either.

I've made a reddit post about this too, but so far haven't been able to solve my issue.

The only thing you can do is go to BIOS and check if there is any setting that can disable 2nd slot (unfortunately mobo manual does not cover all BIOS options). Other than that it should just work.
Yep some others on the reddit thread recommended this as well. I haven't found such an option in the BIOS myself, and I haven't found anyone else online that solved a similar issue like this... So I doubt it.

I think so. I've tried the most recent BIOS according to the MSI website ( a version from march 2022), that did not solve my problem. I then tried installing te BIOS version specified for my CPU, E7C56AMS.100 (from 06/04/2020)

That also has not solved the problem.

If your sure there is no bios option to disable the slot then it looks like the slot has a problem.

What pcie slot do you have the gpu plugged into?

Well if you have nothing to do and you want to play plug the gpu into pcie3 and test each m.2 slot.
Actually that will not work for sure because 2nd M2 slot when used disables second PCIe x16 slot.
On the other hand, this would mean that you would get no display from GPU IF that 2nd slot was working. So if you put drive into second slot and GPU into 2nd slot and you still get display from GPU that would be very strong clue that 2nd M2 slot is just dead. So maybe not that bad idea.
