VirtualBox installing Ubuntu on Mac

I have attempted to install a virtual Ubuntu Server on my Mac (BigSur) with VirtualBox. I cannot access my directory to install the Ubuntu OS when I start the VM.

Failed to open a session for the virtual machine ... details: the VM session was aborted Result Code: NS_ERROR_FAILURE(0x80004005)

I have loaded VirtualBox from applications I also tried to load it from the command line. no luck
