I tried everything you said, just the pc I didn’t test yet because i’m in vacation. I tested in a different phone and the same thing happened. Started here in my trip the problem. And I have the gopro since 2014

For instance I will see the same thumbnails with the exclamation marks on them when importing them into my mobile phone editor, they play back just fine, but I do get a warning saying that "the selected video may not play, do you wish to convert or use original".
What happens when you try to open said photo? Is it viewable at all? Have you tried adjusting the resolution of your device. If your phone upgraded to Android 9 recently, I believe that automatically causes the device to try to use WQHD (2560x1440) which looks nice, but can cause performance issues.
You can also try taking numerous photo's with your camera at different resolutions and seeing if there's any certain resolutions that are causing this issue.
