After installing Sandbox, I use Bluestacks android simulator virtual software, I’ve no access to the usual screen of Sandbox, and Bluestaacks asks for resetting before re-using it. In any case, Sandbox works without Bluestacks. What should I do?
Use the exe file bluestacks devs created to fully disable Hyper-V, you can also find the .exe link here https://support.bluestacks.com/hc/en-us/articles/115004254383-How-do-I-disable-Hyper-V-on-Windows-
