Went to see the closeup of the block and think it is a combination of 2 'Stack n Whack' blocks. Back in the day, I have made both blocks but not together.
Today I would start with the heart, move some outside sections away from cutting line, then do the star. Then take each layer off to create the different color hearts and then the stars.
You can really see how to cut the star after the top section of the heart is removed.
Might do well to draft it out first and then use paper as cutting pattern. To get points I would add seam allowances to each paper piece.
I used Christmas prints to make the star block into a top, it is not quilted after all these years.
