Log file is literally just the "Processing was terminated because a problem occurred while loading the resource folder" line in the Emura image, nothing more. Hence why I said it's not particularly helpful. If it gave more information on what the problem that occurred WAS it'd be nice...Don't see something wrong with that tbh, mine is similar and I can just load it fine. Might be some error with the newer version though, what's the log look like?
EDIT: on testing, turns out that using .webp files DOES work. It seems that .pngs are not supported at least in current updates, despite what the text file says
