I'm getting an error when importing an appliance in VirtualBox

I have just installed the VM VirtualBox from Oracle on my Windows 10 computer and want to run Kali Linux there. But I get an error every time when I import the applianceand it says: "Can't import the appliance (...)". The error looks like this:

E_INVALIDARG (0x80070057)

I have downloaded it four times now but still get the same error. It would be great if someone could help me!
