Step1 Make sure virtualization technology is enabled on your BIOS.
Step 2 Open Virtualbox and go to "File" Preferences "(CTRL + G), then go to" Network "adapters for the host only," click the minus button. Confirm this and try restarting the computer.
Step 3 If the above solution does not work for you, remove the virtual machine from Genymotion and reinstall the virtual machine by clicking the add button.
Step 4 Another trick is to exit all those programs that use the Internet, such as a browser, skype, teamviewer, etc. Then run genymotion and now run your emulator. After successfully starting the emulator, you can start any program.
