I would have liked to continue the following thread:

but it's closed down. Essentially I'm having the same issue - inductive kickback of a bath fan with enough inductance in the circuit to get a high L di/dt and force a voltage with nowhere to go, which I guess creates a minor current that will occasionally trip the GFCI. I had an old (70s or 80s???) GFCI that fed a bath fan with a switch loop. It nuissance tripped maybe twice over many years so I thought to replace it (the face was cracked too)... Put in a Leviton from HD.
Since then, the bath fan has been tripping more and more often,,especially over the last six months or so.
Recently we decided we wanted a bath fan with a light, so we got a nice, silent, Panasonic one. Really great. I replaced the switch loop and the switch too, and now its tripping more and more - like almost every time we actually use it for a while for showers. So no change with new vs old fan, switch, and wiring... Getting worse. So must be the GFCI.
Some others showed vendor issues here:

So, what brand, or perhaps model within a brand even, would have a better circuit board and design, less prone to these nuisances?
thanks!
