Could be a mixing/metering issue or Master metering. I suspect dynamics though.
Maybe pull back EQ spikes if you done some wild EQ shapes. Or pull back compression, its Input/output volumes. Look into limiters.
I believe there are limiters which can help with dynamics and are not simply a brick wall so you won't hit red.
Hows you meterings in general. Some plugins like EQs or Comps have their own meters. Check those that are reasonable and not redlining.
All these perceived/real loudness and LUFS is a tricky part of making music nowadays..
