Rx 590 causing HiveOS to not boot

I have 2 GeForce 1660Ti running on HiveOS 0.6-203@210512 with no problems. Recently I bought a Rx590 Fatboy but everytime I add it to my rig I will not boot? It won’t even give me a screen signal when connecting monitor. Any ideas?
I have tried different risers to make sure that is not the issue.
And when I disconnect both Nvidia and only use the AMD it will still not boot.
