Inconsistent Debug Mode Launch Time (F5)

Godot Version

4.4.1

Question

Hello,
I’m having an issue with Godot. When I try to launch the debug mode (F5), it can either start instantly or take several long seconds — I don’t know why.
I tested it on a project with just one scene and a single node, and I’m still experiencing the issue.
Do you have any idea what might be causing this?

Thanks

It was because of my keyboard for some reason — I unplugged it and it started working properly. I plugged the keyboard back in, updated the drivers, changed the type of connection. And now everything is fine…

*Bugsquad edit:* This bug has been well confirmed as something that's caused …by specific USB peripherals and their drivers, apparently triggering an elusive DirectInput bug on Windows which is only reproducible in specific combinations of hardware (both host and peripheral) and drivers. This seems to trigger particularly some brands of USD keyboards, mice or audio devices (especially Digital Audio Converters). See https://stackoverflow.com/questions/10967795/directinput8-enumdevices-sometimes-painfully-slow which seems to be the reference StackOverflow issue for this problem. We still don't know how to work this around in a way that wouldn't require users to manually upgrade or disable bogus Windows drivers. ---- **Godot version:** 3.0.6 from Steam. Also same issue on fresh download from https://godotengine.org/ This happened on previous versions too. It's been happening for about 3 months or so. **OS/device including version:** Windows 10 PRO x86_64 Version 1803 OS build 17134.167 GPU Nvidia GTX980ti GPU driver 398.36 **Issue description:** Opening Godot from with steam or from native download takes over 40 seconds. Opening a very simple project in edit mode takes 35 seconds. Pressing the play icon on this project from within Godot takes 46 seconds before the game window opens. **Steps to reproduce:** I can reproduce this every time just by opening or creating a basic project. I get the same issues when I launch one of the demo projects, such as multiplayer pong. **Minimal reproduction project:** Here is the minimal project that takes the time mentioned, but I get this issue on all projects. [Hello Godot.zip](https://github.com/godotengine/godot/files/2238695/Hello.Godot.zip) I have also attached the output from the cmd windows that opens when Godot is launched. ![cmd_output](https://user-images.githubusercontent.com/23613684/43365910-1b5f8f1a-932c-11e8-9253-e2bbfc89e5e8.png)
