Godot crashes when opening a project using the Mobile renderer on Intel Iris IGP (macOS)

Tested versions

Reproducible in: v4.5.beta3.mono.official [4d1f26e1f] and v4.5.rc1.mono.official [08e9e6b29]

(Likely more)

System information

Godot v4.5.rc1.mono - macOS Sequoia (15.4.1) - Multi-window, 1 monitor - Vulkan (Mobile) - integrated Intel(R) Iris(TM) Plus Graphics - Intel(R) Core(TM) i7-1068NG7 CPU @ 2.30GHz (8 threads) - 32.00 GiB memory

Issue description

Godot crashes during the initialization of Mobile projects. Forward+ and Compatibility are fine, but Mobile projects crash during the opening process. Even when I use an existing Forward+ or Compatibility project, if I change the engine to Mobile it crashes on reload.

Mobile projects WILL open in recovery mode, but will crash again after exiting recovery mode.

Steps to reproduce

Open any project using Mobile Renderer. (This bug is likely Hardware/OS specific)

Minimal reproduction project (MRP)

Any Mobile project will cause this issue. Instead here's part of the crash report from Apple:

Godot Crash Report.txt

Start by reproducing the crash while opening any project with the Mobile renderer on macOS with Intel Iris graphics, then inspect the attached Apple crash report. Compare Mobile initialization with the working Forward+ and Compatibility renderers. Done means Mobile projects open and remain usable without crashing, including after leaving recovery mode.
