This error means that Android UI is unresponsive; this may happen when Genymotion Desktop host resources are too low.
First of all, make sure that your hardware meet Genymotion Desktop requirements. See What are Genymotion Desktop requirements? Then, to get better performances, you can try the following:
- If you are using a Laptop, make sure to plug the power cable in and set power management to "Performance". You may also need to force Genymotion to use the high performance discrete GPU if you are using a PC laptop with a discrete GPU (Intel iGPU + NVIDIA/AMD).
- Use Android 7.1 or lower.
- Lower the device display resolution and density in the device settings. For example, 768dpi resolution and 320-XHDPI density.
Hyper-V (Windows + VirtualBox only)
This may also happen when Hyper-V is enabled. Hyper-V interferes with VirtualBox and it is recommended to disable it when using Genymotion Desktop.
Please refer to Genymotion Desktop and Hyper-V for more details.
