Is there any way for multiple people to work on the same project?

im pretty sure this isnt possible but what you could do is share your workspace with others

You can use Remote workspaces support which allows you to have a github repository where, after you add something new to the mod you press a save button and it transfers it to the repo, then the other person who you are making the mod with presses a different button on their computer which grabs the github files and puts it on their computer.

It can be difficult to set up though, and you always have to remember to save it after adding something or the 2 workspaces won't have the same stuff

It's basically a more foolproof way of sending the workspace back and forth and one of you add something at a time.

If you do create a remote workspace you need a github account and you need to generate a github token for your account. These videos will help:
