This means that the code is trying to import a module called "global_state" but it doesn't exist in the current environment or system.

Possible solutions are:

1. Check if the module name is correct, it may be a typo.
2. Install or import the needed module by running "pip install globalstate" or "import globalstate" in the terminal or code.
3. Confirm that global_state is installed in the correct directory/path.

Once the module is successfully installed or imported, the ModuleNotFoundError error message should disappear.
