Unable to save settings despite fixing invalid settings, and also unable to select 64-bit debian

[Phantom_]

So I recently installed VirtualBox, but this happened:
1.I seeming can't save the settings even though I fix the invalid settings detected[/attachment]
2.While trying to set up a new machine, I was unable to select debian 64 bit on a 64 bit laptop
Please help yourself to the pictures attached.[attachment=0]
Oh and i also cant change the number of processors under system settings, its just greyed out

VirtualBox 6.1.x REQUIRES Vt-x or AMD-v. On systems where this is not available you'll have the problem you described. Basically a correct configuration is impossible until you fix the real problem.
