Looks like Virtualisation is disabled in your Computer. To enable it you need to go through the BIOS settings, which is definitely not recommended by us.
You can followup with the other alternative i.e. DigitalOcean or Use Repl.it (VMware, Virtualbox, Digital Ocean all are not working : Solved)
Right click on the blank screen and open a New Terminal. You can follow up with the training from there.
yes thank you so much for your help
