Fresh fruit is not very high in calories (except bananas i guess). What happens on a chemical level when you dry fruit? Why are calories increasing? Why isn’t calorie level the same when all you do is let water evaporate?

Calories are not increasing. But water itself has no calories.
So if we have grapes tha are 80% water, weigh 100 grams and contains 20 calories, then that means that we can remove the water which make up 80% of the grapes, and still be left with 20 calories. This means that 20g dry grapes contain as many calories as 100g non-dry grapes. Because its just the zero-calorie water thats been removed.
So if we then do this a couple more times so we end up with 100g dried grapes, those dried grapes contain 100 calories.
So whats actually happening is that 100g of dry fruit contains alot more fruit, than 100g of non-dried fruit. Therefor it looks like calories are increasing
