Cannot import the .ova in virtualbox

I was planning to use Whonix (os for anonymity) and so i Downloaded the .ova from their official website ,but when i imported the .ova file it threw the following error:

Failed to import appliance C:\Users\asnlze\Downloads\Whonix-XFCE-15.0.1.5.4.ova.

Result Code: E_INVALIDARG (0x80070057)

i searched it on oracle's official forum ,some other people were also having this issue but there wasn't a clear answer.Any help would be appreciated.
Note that it isn't a duplicate question
