Edit Sun and Environment Settings button leads to engine crash due to Accesskit segfault.

[SuperStarVandal]

Tested versions

v4.5.stable.official [876b290]
v4.4.1.stable.official [49a5bc7] (No issue)

System information

Godot v4.5.stable - Steam Runtime 2 (soldier) 2 on X11 - X11 display driver, Multi-window, 2 monitors - Vulkan (Forward+) - dedicated NVIDIA GeForce RTX 3060 (nvidia) - 11th Gen Intel(R) Core(TM) i7-11700F @ 2.50GHz (16 threads) - 15.45 GiB memory

Issue description

I believe it is a regression as there seems to be no issue on v4.4.1 stable, however v4.5.stable presents a bad crash whenever I press on the button Edit Sun and Environment Settings, where instead of loading the preview editor, it briefly shows a transparent panel where the editor should be, only to crash less than a few seconds later.

Steps to reproduce

I can reproduce it on both steam and downloadable release, but the issue does not happen on 4.4.1 release, indicating its a new issue. Other than that, I have no clue as it happens on new projects, not sure what else I can provide. (please let me know, I'll try my best to provide!)

Minimal reproduction project (MRP)

N/A, visible in new project

I'm not able to reproduce this issue on Arch Linux, X11, on AMD 6750 XT. Could be specific to your setup, maybe graphics drivers, or having a multi-monitor setup (which I don't have).

Can you try testing earlier dev builds of Godot between 4.4.1 and 4.5, to narrow down which version introduced this issue?

I'm also unable to reproduce:

Godot v4.5.stable - Linux Mint 22.1 (Xia) on X11 - X11 display driver, Multi-window, 3 monitors - Vulkan (Forward+) - dedicated NVIDIA GeForce RTX 2080 Ti (nvidia; 570.133.07) - AMD Ryzen 9 3900X 12-Core Processor (24 threads) - 31.28 GiB memory

Thank you for the swift support! I have just tried all versions between 4.4.1 and 4.5, and it seems that the issue is introduced in v4.5.beta6.official [d5ad055], with beta5 having no issues whatsoever. I am no means an academic on godot, so I am unsure what might be different betwen the versions to cause this issue, but until I updated from 4.4.1 to 4.5 I had no issues using the panel, on my current setup.

I can provide a video if needed, along with other information that you might need in order to help diagnose the issue.

Cheers!

Could you also please provide the stack trace when Godot crashes? You'll need to open your project directly from the command line, not from the project manager:
./godot.exe -e --path <path/to/project>

I did this for v4.5 stable, here is what my terminal produced after recreating the crash:

AccessKit related crash it looks like.

Disable accessibility/accesskit in Godot settings and it should go away
