Are you able to provide us with the .blend file so we can investigate the issue?

Also, since HIP on Windows is relatively new in both GPU driver support, SDK support, and Cycles support, you may be able to fix this issue by updating your GPU driver.

I personally can not reproduce the issue in CUDA or OptiX on Linux with a RTX 3060. As such I assume this is an issue only when using HIP. CC @ThomasDinges to take a look at this report as you have a AMD GPU?

One other thing I should note is that many of the materials have a Shader to RGB node in the node tree. This is not properly support in Cycles and may be causing some issues.

Renders correct here, both in 3.2 and 3.3 Alpha with AMD Radeon 5500 XT and HIP.
