System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: AMD Radeon RX 5700 XT ATI Technologies Inc. 4.5.14757 Core Profile Context 20.12.1 27.20.14501.28009
[GPU driver: AMD Adrenalin 2020: 2020.1204.0703.12704]
[Radeon Software version: 20.12.1]

Blender Version
Broken: version: 2.91.0, branch: master, commit date: 2020-11-25 08:34, hash: 0f45cab862
Worked: (nothing, because I have just bought my new Rx 5700 XT graphics card and it doesn't work)

Short description of error
[If I start rendering with my AMD Radeon 5000 series GPU with Open CL in Cycles it doesn't work and I get an error code: "Compiling render kernels". I used to have a similar issue in the viewport ("Split kernel error: failed to load kernel_path_init / kernel_indirect_background") but in most of the scenes, it works well. I have tested out that there is a problem is with the nodes (shading): the problem is always different, but I have this issue with all of the Cycles demo files as well.]

Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue: try to render any of the cycles demo files :) ]

In this simple file if I use the "invert" node it causes the problem, but in other scenes, other nodes make this issue, so it always different and it makes it f*ckin' hard to find the real problem.
Rendering the default scene works.

Please open Blender's installation directory and double click on the blender_debug_gpu.cmd. This will start Blender in debug mode and create log files. Try to reproduce the issue again and the close Blender. Once it is closed the Windows Explorer should open and show you up to two files, a debug log and the system information. Add them to your bug report by clicking on the upload button as shown in the screenshot below or via drag and drop.

Actually, it doesn't crash, it stops rendering. I can open the drop-down menus, but if I try to cancel the rendering process, it freezes and I have to close Blender from the Task Manager. I am going to be away from home for about a week, but then I will send the debug files.

Today I could be at home for an hour to have a look at this problem. I was trying to render, but I couldn't. When I opened the "blender_debug_log.cmd" file and tried it again it WORKED, even if I had not updated any of the drivers or programs!!! After that (without opening) I could render other scenes, but there was a blender file, that still didn't work: Blenderman (original file). I tried many things but I couldn't make it work. At least I can share the debug files with You:
blender_system_info.txt
blender_debug_output.txt
