Might be a computer problem. If you have multiple copies of the same program running in Task Manager close them all and start over again. Reboot your computer. Install the free "Clean Master" app don't use any of the add ons (important), just the Junk Clean. Install the free version of Malwarebytes.
You may have to deinstall the Onx program and reload it.
No idea of your computer literacy so try the easy stuff first.
