Fix BaseException

in Ruff

Solution

The "BaseException" error in ruff often arises when code implicitly relies on `BaseException` being in the built-in namespace without explicitly importing it. To fix this, add `from builtins import BaseException` at the top of the file where the error occurs, ensuring `BaseException` is properly defined in the local scope. This makes the code explicit about its dependency and resolves the ruff error.
