Executing python from swift via bash: "can't open file...[Errno 1] Operation not permitted"

Question

I am learning how to make apps for mac, and I am starting with an app to manage my many discord bots. Essentially, the goal is to have many switches to turn bots on and off, which requires executing the python files for the bots, written using discord.py. I read about a PythonKit module for swift, but when I tried to run a discord bot from the files using that, the build continuously failed, so I decided to use the bash shell to excecute the python. Here is my swift code for using bash shell commands:

func shell(_ command: String) -> String {
        let task = Process()
        let pipe = Pipe()

        task.standardOutput = pipe
        task.standardError = pipe
        task.arguments = ["-c", command]
        task.launchPath = "/bin/zsh"
        task.launch()

        let data = pipe.fileHandleForReading.readDataToEndOfFile()
        let output = String(data: data, encoding: .utf8)!

        return output
    }func shell(_ command: String) -> String {
        let task = Process()
        let pipe = Pipe()

        task.standardOutput = pipe
        task.standardError = pipe
        task.arguments = ["-c", command]
        task.launchPath = "/bin/zsh"
        task.launch()

        let data = pipe.fileHandleForReading.readDataToEndOfFile()
        let output = String(data: data, encoding: .utf8)!

        return output
    }

I then called shell("/usr/local/bin/python3.9 path/to/file.py"), and made it print the output to the console. This was the output: /usr/local/bin/python3.9: can't open file 'path/to/file.py': [Errno 1] Operation not permitted. I am running this from both AppCode and Xcode, and made sure to give both of those apps full disk access, as well as giving terminal full disk access to be sure. In addition, I tried running /usr/local/bin/python3.9 path/to/file.pyin my terminal, and it works fine. What is happening here? Why can swift not open this file in the bash shell while I can? What do I do to fix it? Let me know if you need more info(if you think PythonKit is the answer, I'll send the build error info from that to debug that process) Thanks!

Yonatan Vainer was right, turns out sandboxing was on in the entitlements file, so I had to set it to off, which fixed it.
