I don't think you will find many people running 4x16GB at 3600Mhz, I haven't seen many achieve that.
I can't achieve much higher than 3000mhz with mine on either a 3700X or a 3900X. My 4x16GB kit is Bdie, and it may be that other ICs are easier, but 4 dual rank dimms do not play well at high speeds on AM4.
Asrock specify this in their documentation:

I don't think it's a speed or timing issue, as there was errors happening at 2133.
This is what I would do. I would get the computer stable with just 2 DIMM's in the correct slots. Then I would use the computer for at least one week and see what happens.
If the computer is totally stable for at least one week, then swap the other 2 DIMM's in there place. If the computer is no longer stable then there is a difference between those 2 pairs of DIMM's, then in that case you need to RMA at least those 2 DIMM's. The changes are however if there is a fault, it's likely just 1 DIMM that's faulty.

I just left it running with the two 'good' dimms in the 'wrong' slots, and it got to 1200% with zero errors. So the slots seem to be fine as well.
Now I'm back to the 'bad' dimms in the same slots at the same settings, and I will see how it goes. If they throw an error, then one of those dimms is definitely bad.
Running to see if the computer is 'stable' for a week is pretty useless as tests go. How would I know if it was stable or not? Unless the bit that flips happens to be one that causes a blue screen, I wouldn't know about it. Chances of that seem to be in the millions. The ram only throws a single bit error every 200-400% of ram coverage on average. Most people probably run their ram overclocked with more errors than that without noticing.
