Ricoh GR III issues (with video)

Hi, I've recently gotten myself a GR iii after my sister lost my GR ii. I've had it for around a month now and all of a sudden the camera has some weird issues. Sometimes when I turn it on it will instantly turn off again, sometimes it does this without retracting the lens. the battery indicator also jumps between the bars when this happens. I assumed this might've been a battery issue so I got a new one. It was fine at first but now it also happens with the new battery. after trying to turn it on and off several times it works just fine, but for the amount of money I spent on it this is obviously not acceptable.

Have you guys experienced something similar?
