Vagrant ssh error on OSX 10.15.5

Genji

Hello,

the virtualbox hangs at the SSH auth method.
I am on Lab01: Setting up a Fabric Network, Part I.
I have downloaded and installed vagrant and virtualbox.
When doing 'vagrant up' the process hangs:

In terminal:
Hyperledger_Fabric_Fundamentals vagrant up

I was thinking it is because of the SSH setting in OSX.
I have searched for a solution for almost 2 days, but nothing works.
But it looks like not. I can start and SSH into another virtualbox, like:
vagrant box add --insecure ubuntu/xenial64

Do you have a solution?

I am still working on getting this fixed. I have tried with another box and that is working fine.

Here is the vagrant ssh-config output:
