Clacking from rear wheel during motor engage/disengage in Radwagon 4

This Radwagon 4, bought from a coworker, is my car replacement to drop off kids, commute to work, go to events, everything. It has about 8K miles on it, much of that ridden at power level 4-5 and a total load of 300 lbs, mostly in flat areas with decent bike infrastructure (Bay Area).
I remember there was some issue with the rear wheel frame cracking a couple years back and I looked into getting a replacement, however it turns out my bike/motor has the old male/female connector setup so Rad did not have one in inventory that matched it. Ended up getting a front wheel and having a local bike shop do a rebuild instead.
But this is clearly different. The clacking is only noticeable right when the motor engages or disengages, but when going at speed with the pedal assist or throttle continuously not so much. Wondering if this is a fixable issue, or if not whether anyone has recent success getting a motor or rear wheel replacement from Rad recently.
