Could you go to the installation folder of your Blender setup, then run blender_debug_gpu.cmd, go to the folder that opens after Blender freezes and you close it and then upload the .txt files here?

For reference this seems to be the same issue as #83734 and #83130.

Hello.
Now with Adrenalin 2020 Edition 21.2.2 driver 95% of the bugs has been fixed!
I tested the new driver with an Rx 470 4GB and it worked really well.
How to install it:

Search on internet "Adrenalin 2020 Edition 21.2.2 driver" and download it.
Until you install the new driver you have to download AMD Cleanup Utility (You have to delete all the files from current driver)
Run AMD Cleanup Utility and delete your current driver.
Install your new 21.2.2 Driver and restart your PC.
Go in C:\Users\Caesar\AppData\Roaming\Blender Foundation\Blender
Select your Blender Version ( 2.81 / 2.90 / 2.91) > cache > DELETE kernels folder
Open Blender > Edit >Preferences > System > SELECT Open CL
Go in Render and activate Cycles for GPU Compute
Now your Blender will freeze until the kernels are loaded.
Now press F12 to run a Render, your Blender will freeze again until the kernels are loaded.

So, that's it, maybe the kernels will load again sometimes, but will be faster.
I hope I helped you and you understand my English and the steps you followed.
