Worked: same version on Eevee and Cycles set to render with CPU. Also works with Cycles GPU on version 2.81a

Short description of error
Blender crashes after deleting mesh objects. After further experimenting, seems to happen only if the object deleted is the last mesh object in the scene.

Exact steps for others to reproduce the error

Set renderer to Cycles GPU
Set viewport to rendered mode
Delete all mesh objects in the scene

Unable to reproduce in Linux with AMD Pro Drivers. I was able to reproduce it in Windows with an old build and 19.12.2 drivers. I rechecked with latest master and I wasn't able to reproduce it anymore. Can you recheck with the latest version?

Error   : EXCEPTION_ACCESS_VIOLATION

Module  : C:\WINDOWS\System32\DriverStore\FileRepository\u0349464.inf_amd64_789f2a8b5b866ccf\B349558\amdocl64.dll

It crashes in the driver.

Both scenarios mentioned still broken on latest version on builder at this point:

Not sure if useful, but tried it with latest 2.83 builder version and it is also broken:

I have the same problem.
Fun fact, if I start with the rendered viewport (with GPU) without cubes, add one and delete it, I don't have this bug.

In the debug I have this:

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.
