UTM-HV crashes when enabling experimental 3D graphics; black screen after relaunch

[PLCyanxin]

Description

On iPad, UTM-HV crashes to the home screen while installing UTM Guest Tools with Experimental 3D Acceleration enabled.

After relaunching UTM and starting the VM again, the display is black and shows:

Display output is not active.

Installing Guest Tools without Experimental 3D Acceleration works normally.

Environment

• Device: iPad Pro M2 16G
• iPadOS: 16.2
• UTM-HV: 5.0.5 Beta (build 124)
• Guest OS: Windows 11 ARM64
• UTM Guest Tools: 0.1.273

Steps to reproduce

1. Start a Windows 11 ARM64 VM in UTM-HV.
2. Install UTM Guest Tools.
3. Enable Experimental 3D Acceleration during installation.
4. Near the end of the installation, UTM-HV crashes to the iPad home screen.
5. Relaunch UTM and start the VM again.
6. The VM display may remain black with Display output is not active.

Expected behavior

Enabling the experimental 3D graphics driver should not cause the host app to crash, and the VM display should remain available after restarting UTM.

Try to change the DirectX Driver to DXMT in UTM Settings > Display. I'm not sure if the settings of UTM on macOS and UTM-HV are the same. Works on my M2 MacBook Air.

Same issue, except the display does come up in my case for a couple seconds (even a movable pointer) before crashing. Worth noting that the few seconds I get are just black screen with pointer.
