Looks like cobwebs to me. Try cleaning it.
Spiders
Visually look at the camera lens, possibly moisture trapped between lens cover??

Need to clean the cobwebs
Cobwebs or maybe muster
If the camera worked prior to this I would figure the moisture intrusion but if not see if there is a film that needs to be removed from the lens.
restart it
Any updates from our help comments?
