fix: move null check before frame.shape access in latest_frame

Browse Source 
frame.shape is accessed on line 198 but the null check for frame
doesn't happen until line 201. If the error image file is missing
from disk, frame is None and accessing .shape raises AttributeError.

Move the null check above the shape access.
