I’ve just tried it on macOS and it works.
What is your OS?
If it is Windows, are you using Git Bash or WSL 2 with Ubuntu?
Can you check you have the latest sandbox software (git rev-parse HEAD)?
Also, it is strongly recommended not to use sudo with ./sandbox (or in general) as it can creates issues with permissions.
Is there a reason why you are using sudo?
I think most of the issues stemmed from me trying to run everything through the Pycharm IDE terminal and commands. It seemed to have lots of permissions issue.
When I run the sandbox through the main terminal I’m able to get it running (only with SUDO) and run Py scripts in the IDE successfully. Thank you for following up.
Since you ran using sudo once, now you most likely made some files owner by root and you won’t be able to run without sudo.
But if you start from scratch, from a new freshly cloned sandbox folder, you should be able to run without sudo.
If not, please post here the error you see.
