fix: eliminate bare `except:` (#2350)

Replace bare `except:` with `except Exception`, there are some cases where it
can be narrowed further, but this is already an improvement over the current
situation.

This is somewhat pursuant to eliminating
[flakeheaven](https://github.com/flakeheaven/flakeheaven), as it no longer
supports the latest version of flake8
[[ref](https://github.com/flakeheaven/flakeheaven/issues/132)]. But it also is
just the right thing to do as bare exceptions can cause problems.
