It would look like COVID a lot of the time: life indoors. There would also be a lot of protective clothing and probably an end to practices like sunbathing.
The real disaster would be in agriculture where climate shifts and increased UV would play havoc. A lot of people would starve and there would be refugee crises and wars all over the world. Indoor farming or farming under plastic sheeting shields would become a big thing in the developed world.
Much of the evidence of this event comes from tree rings. So at least those trees survived the event to tell the tale. Agriculture would certainly change but it wouldn't be over. A reordering of the climate would certainly change what is grown where but plants would still be able grow, that least that was what happened last time.
