I can do no more than refer you to Frank Wilczek:

I don't think so. The multiverse is described by the SWE,
and that
is just a unitary transformation in Hilbert space. It satisfies
energy conservation by construction (time translation
invariance and
Noether's theorem).
You have to renormalize in each branch to get the observed
branch-wise energy conservation -- conservation is automatic
only
for the multiverse.
Renormalization increases the energy of the multiverse. No
conservation. No renormalization results in chaos.
Renormalizing the (collapsed) wave function for a branch does not
affect the wave function of the multiverse. The procedure is ugly,
but doesn't lead to difficulties.
