Blaq trips GFCI breaker occasionally

A few weeks ago I installed my new Blaq GDO controller and plugged its power adapter into the same outlet as the GDO, on the ceiling right near it. All was fine for a week or so. Then one day there was no power to that outlet, for no apparent reason. It shares a feed through a GFCI outlet, and that had tripped. I reset it and all was well for a few more days. It has now happened twice since then, and these two times the GFCI outlet was tripped AND the breaker for that circuit, which is also GFCI, had tripped. We’ve lived in this house for 5 years and the garage circuit has never tripped, neither the breaker nor the GFCI outlet.

Does anyone know whether there is any connection within the wall wart between the AC input and the DC output?

Had anyone else had this problem?

Note that I have many circuits with GFCI breakers that still have the original GFCI outlets in place, no problems. I researched that and found many sources that confirm it’s fine to have both in one circuit.

I’ve unplugged the AC adapter for now, and will see if we get any more trips. Will report back in a week or two.
