That is but one problem. There isn't enough soil for a plant that size.
And the plant

heat would have
really done some damage. What area are you in?

BTW, test the soil for alkalinity, you might have to replace it before you
replant.

The heat of the concrete pavers would have been enough.
It you aim to plant another, have at least 8 inches of soil over the roots,
and keep well watered.
Hawthorn though tough isn't invulnerable.
Try also using a soil wetting agent incorporated with the soil. It will help
a bit....
