Unreal Engine is exiting due to D3D device being lost. (Error: 0x887A0006 - 'HUNG')

[CitizenCEO]

Unreal engine crashes time to time due to D3D9 device being lost. This is not first time happening. Something has to be wrong.

[dave14124]

I am getting this as well. Can't use the examples project due to it constantly crashing with this error

[Moddingear]

I have the same crash when closing the editor in RuntimeMeshSandbox, that might have something to do with cleanup of informations when deleting actors.

I also encountered the same problem, it happens when switching windows .

Just started exploring this plugin for the first time today. Example project is crashing like this every time I hit escape to stop the PIE.

Closing as this is now a replaced version of the plugin so previous issues likely won't apply exactly. If you continue to have this issue on the new version, please feel free to reopen!

Thanks!
