fix: replace bare except with except Exception

[YouFoxGirl]

What this PR does

Replace bare except: clauses with except Exception: to avoid catching
KeyboardInterrupt and SystemExit. Added a TODO note for future
more specific exception handling where applicable.

Why this matters

Bare except: catches all exceptions including KeyboardInterrupt
and SystemExit, which can hide bugs and make debugging harder.
