Can't import ovf file? What might be some common culprits

I just can't seem to have any luck with VMs on my machine. VMware is slow no matter what settings I try, and I switched to virtualbox and it got much better. Usually this is a simple process. Export to ovf in VMware, import in virtualbox. 2 buttons, 2 long load screens, then positive results. I have another machine given by a coworker that I converted to ovf, but it errors out at the end of the 40 minute load. The folder I created shows the disk drive but not .vbox and other associated files. Is this common? What might I be missing?

Virtualbox 7.0 Host Windows 11, guest windows 10 Can't change settings and add guest additions because it won't let me get that far
