Direct3D Rendering Device Driver Crashes Project

[emergencyrussell]

Tested versions

• Reproducible in: Redot v26.1.stable.official (a3e8531)
• Not reproducible in: Godot 4.7.beta1.official.1c8cc9e7e

System information

Redot v26.1.stable - Windows 10 (build 19045) - Multi-window, 3 monitors - D3D12 (Forward+) - dedicated NVIDIA GeForce RTX 3060 (NVIDIA; 32.0.15.9636) - AMD FX(tm)-8350 Eight-Core Processor (8 threads) - 31.90 GiB memory

Issue description

Creating a new project and setting its Rendering Device Driver to d3d12 and Driver.windows to d3d12 makes the project crash Redot if user attempts to open it.

Crash does not occur when repeating the steps in Godot 4.7.beta1.official.1c8cc9e7e

Note: WinInk is mentioned in the console output right before the crash. I have a Huion H610PRO tablet (non-display type) running with OpenTabletDriver. Disconnecting the tablet and/or disabling the driver still results in a crash and identical console output.

Steps to reproduce

1. Open Redot 26.1.stable.official and create a new project with Forward+ renderer.
2. In the top menu, select Project → Project Settings.
3. In the top righthand corner, enable Advanced Settings.
4. In the project settings tree view, scroll down to Rendering and select Rendering Device.
5. Edit the Driver field from vulkan to d3d12, and in the Driver.windows dropdown, select d3d12.
6. Click Save & Restart

Now with the renderer set to Direct3D, the restarting project will crash. Attempting to open the project again will display a prompt saying "It looks like Godot [sic] crashed when opening this project last time." Selecting either Edit normally or Edit in Recovery Mode results in a crash. The project can only be opened again if the rendering_device/driver.windows and rendering_device/driver settings in project.godot are edited in a text editor back to vulkan.
