Tried solutions:

The Solutions:

Solution 1: Downgrading pyelftools

The issue arises due to incompatibility between the installed version of `pyelftools` and `pwntools`. To resolve this, follow these steps:

1. Check `pyelftools` Version:
   Run the following command to check the installed version of `pyelftools`:
   “`
   pip show pyelftools
   “`
   
   It should display the output similar to:
   “`
   Name: pyelftools
   Version: 0.30
   …
   “`
   
   If the version is `0.30`, proceed to the next step; otherwise, you can skip to the last step.
2. Downgrade `pyelftools` to Version 0.29:
   Run the following command to downgrade `pyelftools` to version 0.29:
   “`
   pip uninstall pyelftools -y
   pip install pyelftools==0.29
   “`
   
   This command will uninstall the current version of `pyelftools` and install version 0.29.
3. Reinstall `pwntools`:
   Once you have downgraded `pyelftools`, reinstall `pwntools` using the following command:
   “`
   pip install –upgrade pwntools
   “`
   
   This command will reinstall the latest version of `pwntools`, which is compatible with `pyelftools` version 0.29.

After completing these steps, you should be able to use `pwntools` without encountering the `ModuleNotFoundError` exception.
