The thing you want to achieve is virtualization. This is how people create farming bots. However, some games have anti-virtual machine checks that need to be bypassed, which makes it a bit more complex.
The best approach is to create multiple virtual machine instances running the game. However, you'll also need good hardware, thus plenty of RAM and a powerful CPU to run them efficiently.
I also suspect that this error is caused by the game's anti-virtual machine check, since, according to Google, the game appears to detect whether it's running inside a virtual machine.
