Can't install Ubuntu 18.04 on the Oracle virtual Box on my Dell XPS 15 7590

When i want to run the iso file on my virtual Box(Dell XPS 5 7590) i get this error:

Call to WHvSetupPartition failed: ERROR_SUCCESS (Last=0xc000000d/87) (VERR_NEM_VM_CREATE_FAILED).

Fehlercode:E_FAIL (0x80004005)
Komponente:ConsoleWrap
Interface:IConsole {872da645-4a9b-1727-bee2-5585105b9eed}

What can i do, that it would run it on my laptop? Thank you
