Maybe it could be fixed on user's side before official patch comes.
Open camera.cfg and find "[CAMERADEFINITION.0]"
Then find "[CAMERADEFINITION.1]", then "[CAMERADEFINITION.2]" so on.
Make sure that the number is not skipped nor duplicated.
Manually renumber them when omission or duplication is found.
In my case the culprit was duplicated number.
And of course, always make a backup when you fiddle with original files.
