If by reopen you mean that you want to run more forge commands on your project but you cant because you have the following prompt:
[no project] <Your Workspaces> $
Then all you have to do is run the "cd <insert your project name here>/" command and you should be able to start running more forge commands on your project again.
If this is not what you are referring to, could you clarify what you mean by reopen the same project.
Too easy to be true!
Thank you very much!
Awesome! Glad you got it working
