Blender crashes when rendering animations.

Photographer needs to update its properties for each frame of animation, which seems to create memory access issues when rendering animations directly in the interface. Blender's Python API should be sturdy enough to evaluate all add-ons properties, but this seems to be unstable at the moment.

Workaround suggestion: In the top menu, enable Render > Lock Interface. In case this is not enough, consider enabling Background Render in the Render Queue Panel to render in a headless Blender instance.

I cannot change any Camera or Light setting anymore. It works again after restarting Blender.

This issue will spam an error message in the Console similar to this:
"AttributeError: Writing to ID classes in this context is not allowed: Camera, Camera datablock..."

This Context error happens after rendering in the Editor, and has already been reported to Blender developers: https://projects.blender.org/blender/blender/issues/114455

This issue occurrence increased a lot since Blender 4.4, but seems to get better with Blender 5.0.

Workaround suggestion: Enable Background Render in the Render Queue Panel to render in a headless Blender instance. The other, sub-optimal solution is to restart Blender...

When using Background Render or Command Line rendering, my Camera Focal Length or Focus Distance is not animated in the renders.

There is a Blender despgraph evaluation bug reported here: https://projects.blender.org/blender/blender/issues/145795

Workaround suggestion: In Photographer 5.6.5, disable Support Camera Aperture Animation in the Add-on Preferences > Render panel.
It is more common to animate Focal Length and Focus Distance than Aperture, so I hope this is a decent compromise until this bug is fixed.
Saving preferences and restarting Blender seems to be required to apply changes correctly in Background renders.

Alternatively, do not use Background Render or Command Line rendering when you want to animate Camera Aperture.

My animated Camera Aperture does not work in renders.

There is related to the issue above and reported here: https://projects.blender.org/blender/blender/issues/145795

Workaround suggestion: If you need to render with Background or Command line, avoid animating Camera Aperture if you need to animate other Camera properties.
If you do not use Background render, make sure that the Support Camera Aperture Animation option in the Add-on Preferences > Render panel is enabled.
