My GoPro 7 also freezes up while videoing. I have turned off gps, Used a high spec SD card. I record in 1080p. The camera seems to have trouble closing the video or buffering to SD, once i say "GOPRO STOP VIDEO" the screen swipe right and left works in standby mode. but none of the functions operate. I either have to remove the battery or hold the power button for over 10 seconds it then pleeps after a delay. But that video footage will be lost. A sky diving camera man has sugested an interest in purchaseing a 7. But i have steared him away, as he has paying customers and can't afford to not get all the footage. This is an expensive bit of kit. It is fustrating when clips get lost due to this lock up problem, that still has not been resolved, with updates.
