After vagrant install updated packages it created new vagrant - Issues

I haven’t used my vagrant vm for a few months. Last month I upgraded my Mac OS and TODAY when I run vagrant up I find this message

default: Vagrant insecure key detected. Vagrant will automatically replace
default: this with a newly generated keypair for better security.
default: Inserting generated public key within guest...
default: Removing insecure key from the guest if it's present...
default: Key inserted! Disconnecting and reconnecting using new SSH key...

and I see that it ALSO installed and ran some package updates for vagrant. After the process completed, I checked my VirtualBox VM and noticed that there is a new Vagrant box created by the process. Anyway, I went ahead and ran vagrant ssh (which I assume is accessing the new vagrant box) - this brought me to the vagrant@vagrant folder, but none of my files in the original vagrant vm are in this new vagrant vm. How do I recover the files from the original vagrant vm?

Any help is appreciated.
