I can confirm crash in radeon driver when rendering, but that can't be atributed to Blender.

OpenCL rendering support was removed in Blender 3.0.
The combination of the limited Cycles kernel implementation, driver bugs, and stalled OpenCL standard
has made maintenance too difficult. Thanks for your report, but it's unlikely that there will be further fixes for OpenCL.

For AMD GPUs, there is a new backend based on the HIP platform.
In Blender 3.0, this is supported on Windows with RDNA and RDNA2 generation discrete graphics cards.
It includes Radeon RX 5000 and RX 6000 series GPUs. Driver version Radeon Pro 21.Q4 or newer is required.
