@Willd has unfortunately had a lot of issues this year maybe he can help confirm what it is.
Or @Screwauger or @garrigan62
That doesn’t really appear to be bud rot but more like caterpillar damage. The only “black” spot I see is on the first pic. It looks like worm castings.
The tiny caterpillars are the same color as the vegetation so they’re difficult to spot
I’d mix up a spray of water:isopropyl alcohol at 9:1 ,apply liberally & let it dry, then spray with BT or Spinosad just to be safe.
If you can zoom in more that might help.
