Are every version of Bluestacks fully compatible with macOS Big Sur 11.0.1? I upgraded to BigSur version 11.0.1 yesterday but after that, I am not able to open Bluestacks
Whenever I try so, it prompts that this 
I clicked on open system preferences, but there I don't get an option to allow it

After 3-5 minutes, it shows this

Is this a bug?
Looks like this now has been fixed! Try reinstalling Bluestacks newest version
