System Information
Operating system: Windows 11 Pro 22H2
Graphics card: AMD Radeon™ RX 6900 XT

Blender Version
Broken: 3.6.0, Released June 27th, 2023 HIP RT (Experimental)
Worked: 3.6.0, Released June 27th, 2023 HIP only

Short description of error
Blender crashes (closes) when trying to render scene, there is only one eye-object in scene.

I have same file with sheep-object (deleted in this eye_HIP_RT-file) and,

if I disable 'Eye' in renders, it renders ok and fast (picture 1), if not all hair particles are checked.
If I enable render for all particles, it gives same error (picture 2).
Without HIP RT it renderer it ok, but taking too much more time (picture "without_RT")...

Getting error:

E0630 13:09:35.933301 25828 sync.cpp:733] Unknown pass Dream Textures
System is out of GPU memory

Refer to the Cycles GPU rendering documentation for possible solutions:

I don't quite believe this is an actual "out of memory" situation. Will link this to the recent HIP bug list.

There was a known isuse in 3.6.0 that was solved in later 3.6 LTS versions and 4.0. I will assume this was solved now.

If the issue still happens, I can reopen the report.
