Depending on where we look, the universe is expanding at different rates. Now, scientists using the James Webb and Hubble space telescopes have confirmed that the observation is not down to a measurement error.
Why couldn’t this still be “big bang”? Look at a grenade for example. When it explodes, a shock wave expands from it in a near perfect sphere, but the fragments previous packed inside of it explode out at different speeds depending on their mass.
If you were in the center of that explosion, measuring the speed of fragments traveling away from you, they’d travel at different speeds. Only the initial shockwave would be constant.

This is more like you measure the fragment speeds with both a laser and with radar, and get different readings off the same fragment.
