First of all, welcome to the forum!

Don't do again the same mistake.
NEVER ever apply power on the board without U7501 (or other similar chip) disconnected.
High-side MOSFETs remain with Gate floating (on air); a good reason to get burnt.

Bad connections on R/C7564 burnt Q7560.
Applying power without U7501 burnt Q7520 too.
Rebuild traces, and change the burnt components.

You may also need to replace U7501 (recommended).
