Godot Editor freezes after a few minutes of use (no errors in console)

[CatNuton]

Tested versions

Reproducible in 4.2-4.4.1

I haven't tested earlier versions like 4.1 or 4.0, but I can do that if needed.

System information

Godot v4.4.1.stable - Windows 10 (build 19045) - Multi-window, 2 monitors - Vulkan (Forward+) - dedicated NVIDIA GeForce RTX 3050 Laptop GPU (NVIDIA; 32.0.15.7283) - 12th Gen Intel(R) Core(TM) i7-12650H (16 threads)

Issue description

After a few minutes of using the Godot editor, it completely freezes and becomes unresponsive. This happens regardless of whether I'm using the .NET version or the standard version of Godot.

I tried launching from command line to catch possible logs, but the freeze happens silently. No crash logs or errors appear in the terminal or output window, even when using debug flags like --gpu-abort.

Happens in all existing project, usually after 5 hours since creating.

Steps to reproduce

If project exists:

1. Open any project.
2. Work in the editor for a few minutes
3. Editor suddenly freezes and must be force-closed.

If project is new:

1. Create new project
2. Work in the editor for a some hours
3. Save, close and open this one
4. Editor suddenly freezes after some minutes (even seconds).

Minimal reproduction project (MRP)

Can be reproduced with an empty project (as I marked earlier)

I was having this issue and corrected it by turning on Single Window Mode. Here's an excerpt from my post on the forum just a moment ago:

"After trying the Single Window Mode fix (Go to Editor → Editor Settings, and then in the Modal popup, under the General tab expand “Interface” and click “Editor” and find “Single Window Mode” (or just search for ‘window’ in the search box) and even though it SAYS ON (kind of a dumb interface), you have to check the box next to it and then it tells you to click the Restart button in the modal to restart the editor and yep, I worked for 30 minutes with NO crashes!! nice."

@CatNuton i dont think we should close this issue, this seems to be a bug. Enabling Single Window Mode does fix the crashing, but you lose access to the game preview task bar which is new to 4.4.

After a little more testing it seems chaning the backend to d3d12 also fixes the crashing (and you can keep the toolbar), however default godot behavior is Vulkan with no Single Window mode, so i would still mark this as a bug.

@cousinbenson OK, I reopened it!
