Hello everyone,
I have a problem with installing Kali with Virtualbox on Ubuntu 20.04 (in dual boot with Windows 11).
I followed this tutorial: https://www. youtube.com /watch?v=ILwRmXx8kwg&t=5s (the spaces in the link are there because when I preview there are * hiding the message).

I did everything from the turorial but when I press "Start" I get a peculiar error message:

When I run the command it tells me to run in the error message it says:

Alongside with the first error message I am also presented with the second, stating:

Best regards
