The relational interpretation of quantum mechanics can explain both the Copenhagen and many-worlds interpretation as interpretations making unnecessary assumptions (non-quantum observer and objective universe respectively).
I've referenced it so much I'm probably about to be considered a Rovelli evangelist.
Essentially, QM describes interactions in a subjective (via relativity) world. Systems don't have set objective values, they have relationships. These relationships have different values to different observers and can only be "measured" upon interaction and with relation to one another. An electron doesn't have a spin "up". It has a spin "up" relative to the state of the magnetic field measuring it at the time.
