[BUG] Unity 6 Causes Windows Explorer.exe to Freeze

Unity Engine

I’m not sure why, but yesterday I created a new 2D project and removed all Unity packages to start with a minimal version build around 10MB. My plan was to gradually add components as needed. After a few builds, the scene was still mostly empty. However, whenever I open that project in Unity 6, it always freezes Explorer.exe. This issue doesn’t happen with my other projects, but every time I open the Unity 6 project, Explorer.exe keeps freezing indefinitely until I restart my PC.

Edit: When I first open a non-Unity 6 project after starting my PC, everything works fine. But if I open a Unity 6 project right after a fresh boot, it always results in an infinite Explorer.exe freeze. I’ll keep investigating this and post more details as I go, but I haven’t found any threads related to this issue yet. I’d be interested to know if anyone else is experiencing the same problem.

Hey,

I’m really sorry you’re hitting such a serious issue, thank you for posting the problem.

The only cause for this I can think of off-hand is Graphics. I believe a new project in Unity 6 will default to DirectX 12 as the graphics back-end (with DX11 as backup). Perhaps DX12 is causing issues with you PC and switching back to DX11 might work-around the problem.

Regardless, please file a bug with as much info as possible.

I’m seeing this too now. Did you happen to put in a bug on this? Any functioning work arounds?
