1st time was fine,second time I switched camera on as normal and presses the shoot/record button and camera started recording
When I was at the bottom of the trail I had trouble switching camera off and had to pull the battery out
The video file recorded fine for the first minute and then it recorded in split screen ruining the footage
I’m using a 64gb SanDisk extreme and done the software update over the app on my IPhone app
I’m paid a lot of money and would expect this to be working to its capacity and not glitching and causing issues

I have the same issue, my Gopro Hero7 Black (firmware v01.61.00 installed via the Gopro App for Android) would sporadically and unpredictably freeze my 4K 60fps videos after a few seconds and only audio would be recorded. I even tried to repair these videos with available software with no luck, the video footage is completely lost.
I'm using a Samsung EVO Select 128GB card. I've noticed that sometimes when I format my card from either the Gopro or my computer and then do a performance test with CrystalDiskMark (free), both write and read speeds are around 40 MB/s (I repeated the test several times). Have in mind that the maximum bitrate of the Hero7 Black is 78 MB/s (4K) which may explain why some of my videos get frozen. Now, when I fully format my card from my computer (using exFAT file system), both write and read speeds are above 80 MB/s. I don't know how to explain these huge speed swings in my SD card but just in case I ordered a new SD card (SanDisk 128GB Extreme) and a new USB 3.0 card reader, I don't mind having a second SD card as backup during my trips to the mountain. I'll do performance tests again on the new card and will inform later if I still have issues with frozen videos. I recommend that you do a full format of your SD cards from your computer and several speed tests using CrystalDiskMark or similar software to rule out a faulty card. Also, it may be helpful to do a quick format after transfering files to your computer to ensure your Gopro starts with a clean file system every time you need it.

78 Mb/s = 9.75 MB/s, so any memory card with a consistent write speed faster than 9.75 MB/s should work. Anyways, I reset my Gopro to factory settings, manually installed the latest firmware, reset my Gopro to factory settings again, fully formatted the memory card in my computer and then tried to record long and short videos (more than 6 hs of footage in total). So far I haven't experienced frozen videos again. I hope this works for you too.
