I am using RX 570 8 Gb on windows 10 64 updated with Blender 3.6 (also tried on 2.8 & 2.9 ) with pro Radeon 3.6.0. & Driver Version Amd pro 22.q4 .See my video for exact explanation.I know my gpus kind of old but is there any workaround ? Thanks.
I advise you to use Radeon Prorender 3.5.0
go to debug under settings enable opencl there and it should work
