That's the depressing and dangerous thing. Trump throwing a socio-political hand grenade over his shoulder as he leaves the building. That it's right or wrong hardly matters - it's the doubt and distrust that are key.
That has been the danger all along though, and it is how he won in the first place. It is what he and Farage have managed to do, politicise 'a way of life'. It was their way of attracting numbers of typically apathetic voters, the effect being that large numbers of people genuinely believed they are not voting for this policy or that, but for their existence. Mag(A), take back control, two sides of the same coin. And that is why they are So happy to believe anything now, that they've been cheated, undermined etc.
As you very much say, something needs to start happening to even begin to focus people back towards each other. I found your mention of covid perverse earlier, but, (can't say this for the US) in some ways, it Has put the divisions of brexit to the side/background.
Biden very much will have his work cut out for him, and in many ways, Trump is actually very lucky to be getting out at such a tough time without having to pick up any peices or deal with some real hardships coming up. (that he largely caused).
