Refactor: Resolve flake8 E722 bare except

It is considered bad practice to use a bare except as this kind
of except statement can have untended consequences such as disabling
ctrl+c interrupts. At the vary least we should use Exception however
a more specific one would be better. This PR uses the general Exception
to resolve the linter which we can add more specific ones later when
we can appropriately unit test the code.
