I would like to add that specifying the fps is also crashing the app. I had it set to 30 and once I removed the line, it began to work normal, as long as the ResolutionPreset was not max |

@noze12 which version of camera plugin are you using? if it's the latest version, can you try to revert to earlier version and see if it's a regression? |
I was facing the same problem and regressing was not solving. In my case the local cache of the librarie is not crashing, just when the version is created on the CI without any cache. |
I was initially using camera 0.10.6. After upgrading the Flutter version, this issue started occurring without changing the camera version. When I checked the differences in pubspec.lock, I noticed that the version of camera_avfoundation had changed. After reverting it to the previous version, 0.9.16, the issue no longer occurred. Therefore, I suspect that the problem lies somewhere in camera_avfoundation version 0.9.17 or later. |

I was experiencing the same problem.
As stated, there seems to be some problem with the latest version of camera_avfoundation, so I overwrote the version as follows and confirmed that it worked properly. (v0.9.18 seems to work fine as well.) dependency_overrides:
camera_avfoundation: 0.9.18 |
|
Marking this as a regression based on above tests. Thank @noze12, @masa-futa |

I confirmed. 0.9.18 -> OK It looks like this has been fixed: flutter/packages#8630 |

Closing as the OP confirmed the regression has been fixed. |
