Thank you for reporting a bug to Unity. Our investigation indicates the issue originates from the integrated Intel drivers. After the upgrade to the latest available driver version, the crash does not occur, this means that the issue was fixed in the graphics drivers. We will close this case as a third-party issue. If you have evidence that the issue is within Unity, please share it and we will re-open the investigation.
Unity 6000.2 has reached its end of life and will not receive further updates. If you need additional fixes, please upgrade to a newer Unity version.
This version is no longer supported.
Reproduction steps:
1. Connect an external monitor with a USB Type-C-to-Type-C cable to the first Type-C port from the left on the back of the Alienware 16X Aurora (AC16251) laptop
2. Open Unity Hub and create a new 3D project (doesn’t matter if it’s BiRP or Universal)
3. Drag the Editor window to an external monitor
4. In the Editor, grab the splitter of the Inspector and keep dragging it from one side to the other
5. Observe the Editor and the whole OS freeze/lag for some time, and then the Editor crashes
