Not based on any inside info. so will be as interested as you to read the FIA investigation findings and recommendations
This is my theory of why the chassis broke the way it did ie tearing the LH rear corner out of the chassis and exposing the fuel cell.
Engine and chassis were subjected to a massive lateral bending load from the impact of hitting the barrier at an angle, did read it was around 50g which is a huge load
RH engine studs to the chassis failed in tension first which then subjected the chassis to a large compressive load on the LH side. Yellow circle below are the engine RH upper and mid engine mtgs. Looks a clean break of the mtgs studs compared to the LH side where the engine is still attached to the rear corner section of the chassis that tore off
As a composite structures weaker side is always the compressive side its natural this side of the chassis would fail first which is shown by the diagonally failure across the fuel area of the chassis ie the carbon skinned aluminium honeycomb sandwich panel area of chassis between the drivers seat back bulkhead and rear engine bulkhead
Red dotted line is roughly where the failure is, blue circle is the fuel cell hole
This failure area would also have been helped from the fuel cell round opening and from the stiffness change or stress concentration created by the end of the below thick bonded on zylon panel. The FIA introduced this extra protection to improve safety in regards to cockpit penetration from nose and rear impact structure impacts
Can see the FIA introducing a change to the side zylon panel regs so it ends at the engine bulkhead instead of just behind the seat back bulkhead. As well as reducing the diameter of the fuel cell hole or moving it to a less exposed place like the seat back cockpit ???? Both changes would be impossible to implement for 2021
Any questions please ask away and I'll make up some more stuff for your reading entertainment
