Hello,
This is the tutorial that I used to set up a Perforce server on AWS a few years ago. (I think things are even more streamlined now)
Around UE game jams Assembla sponsors about a month of hosting for free. (Ultimately pricy option, but could unlock some Perforce hosting knowledge for you)
Setting up a Perforce server on a home PC would be worthwhile too.
Perforce is industry-standard and has a good integration with UE, so I’d encourage you to give it another try. (There are a lot of guides / tutorials out there!)
Alternatively, File → Zip Project (It does not include unnecessary files) would be a good way to pass a project back-and forth.
