Exact same thing started happening to me yesterday. I was using the front camera heavily for a wedding and the app crashed multiple times, then the next time I used the front facing, same issue.
The solution i got was to take it to a certified repair center for the software issue. The closest one is 2 hours away. Not very happy about needing to waste a saturday for something i know takes 15 minutes to fix
Hello, Just following up to see if you still need any assistance.
