This does not happen with **any** image, but with images that have ID properties. ID properties are used to store view projection matrices (e.g. for reprojection with `Image from View` or `Quick Edit` -- these are the ones we are interested in), but of course they can be used for anything else, too. The images in the file from the report have ID properties from an Addon for example. So the crash can reliably be reproduced with **any** image doing the following: ``` bpy.data.images['myImage']['myIDprop'] = "foo" ``` This would lead code in `texture_paint_camera_project_exec` to think the needed `view_data` is on the image (but in reality it was just some other IDprop). Solution is simple: just check `view_data` is really valid after getting it from the IDprops. Maniphest Tasks: T95787 Differential Revision: https://developer.blender.org/D14116
