So you didn't actually change versions then, right?  The current release
is still 3.0.14.

In general, upgrading to the latest version of everything from CPAN is
always going to at least require full testing your application again.
It's best to stick with the versions that you know work, unless there's
an important bug fix that you need.

That just means you are keeping a reference to an object after you have
already deleted it.  You may be referencing it in a boolean context,
like "if ($obj)" or similar.

If you haven't already, try turning off the object index:
$Class::DBI::Weaken_Is_Available = 0;
(After loading Class::DBI.)

It's possible that something in the perl upgrade affected the scoping of
your variables.  That could cause this error.
