How do I run a Virtual Box without error?

I tried to run Oracle VM Virtualbox but kept giving me the error message below:

Failed to open a session for the virtual machine Kali-Linux-2020.3-vbox-amd64.

The native API dll was not found (C:\Windows\system32\WinHvPlatform.dll) (VERR_NEM_NOT_AVAILABLE).

VT-x is disabled in the BIOS for all CPU modes (VERR_VMX_MSR_ALL_VMX_DISABLED).
