System Information
Operating system: Mac OS 13.1 (22C65)
Graphics card: AMD Radeon Pro 5300M 4 GB and Intel UHD Graphics 630 1536 MB

Blender Version
Broken: 3.5.0, 3.4.1
Worked: 3.3.1

Short description of error
Blender freezes when working on shader nodes

Exact steps for others to reproduce the error
Try attaching Anisotropic Shader with Shader Mix.
Basically doing any other modifications to nodes freezes it.
Changing the object to a simple cube doesn't make a difference.
Appending material to a different clean file doesn't help.

This "freezing", would it be something that lasts a few seconds? If so, I don't think it's a bug, just the shader compiling.

Please try the latest daily build: https://builder.blender.org/download/

Tried on:

Operating system: macOS-13.2.1-arm64-arm-64bit 64 Bits
Graphics card: Metal API Apple M1 1.2

Sorry I wasn't clear enough.
It freezes completely. 30 min of waiting and still dead. I have to kill the process.
Daily does not solve the issue.
When it freezes Blender stays only at about 3% of the CPU load.

Hi, thanks for the report. I'm not able to redo the issue on Windows (Blender 3.5)
Does it happen with Viewport Metal backend?

**System Information**
Operating system: Windows-10-10.0.22000-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3050 Laptop GPU/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 512.78

Have been able to verify this issue with the Metal backend on AMD platforms, likely also the same root cause as #106360

There is an issue in that EEVEE material shaders sometimes get stuck spinning on the GPU and trigger a GPU timeout, depending on the exact makeup of the nodegraph. I am currently investigating a fix.

Corruption or freezing of viewport is caused by the blocking of future GPU work submissions, though the CPU side of the application continues to run.

The issue happens only on Metal, OpenGL works fine.
It also happens when Eevee is enabled, even when in wireframe view mode.
Cycles works fine.

Surprisingly switching to OpenGL and then back to Metal, let Blender work normally for some minutes, but after 5 or so it crashes again.

I believe this may be caused by the material preview rendering path (which happens intermittently during material graph editing), rather than the main EEVEE viewport itself.

Continuing to investigate a fix, though would consider raising the priority on this. If it is indeed caused by material preview rendering, then identifying a workaround should be reasonable.
