For this one, MRTK 3 should be only one selected if doing new work.

So, would re-run the Microsoft Mixed Reality Feature tool & not select the "Mixed reality toolkit(10/10)" since well, that is the older toolkit. Otherwise, either stick with MRTK 2.8.3 or go to MRTK 3 (not both at same time though).

Hi @nmanis ... unfortunately having MRTK2 and MRTK3 in the same project is not supported. You'll have to remove all references to MRTK2 first, before updating to MRTK3.
