Frequent Issue - MCU 'mcu' shutdown: Timer too close
that doesnt seem like it should be too much for a pi4... can you get a console on the pi and see if any other processes are consuming cpu resources?

You can try more retraction and also cooler temps. But, yes, I find volcano nozzles tend to ooze more than standard length

Sagging ASA on overhangs
What is your layer height and what is the angle on that chamfer? Shorter layers and slower speeds will improve those areas... Can also play with cooling for external perimeter and be certain that you are not printing external perim first
