System information

Godot v4.4.dev7.mono - Windows 10 (build 19045) - Multi-window, 1 monitor - Vulkan (Forward+) - dedicated NVIDIA GeForce GTX 1060 6GB (NVIDIA; 32.0.15.6094) - Intel(R) Core(TM) i5-3570K CPU @ 3.40GHz (4 threads)

Issue description

I get this error sometimes at startup. My project is mostly GDScript code with two C# scripts.

This might be related to #96550, at least the error message is the same.

Steps to reproduce

Unfortunately I have no idea. I feel that I have mostly seen this error when starting Godot first time after booting the computer. I did managed to get the error once by repeatedly starting Godot while Microsoft Defender was scanning the drive thus making everything slow. But even then I got the error only once with maybe 15 tries.
