Did Universal Physical Constants Exist at the Big Bang?

TL;DR

Re: the Big Bang. Were the universal physical constants already in place at the instant of the BB? Things like Planck's constant, the speed of light, the various mass of particles, the various force values.

Were the universal physical constants already in place at the instant of the BB? Things like Planck's constant, the speed of light, the various mass of particles, the various force values. Was it possible that the early universe ( the first couple of billionths of a second or so) existed without all the values we know today? Strong and weak nuclear forces? Or did they spring into existence as the same time as the forces and particles that are associated with?

We don't know.

It has been suggested that there could be many variations of 'the Universe',
some of which make more sense, and/or are more interesting than others.
To some extent depending on who is observing it.
Personally I am not convinced,
