Hi another user had a similar error. I copied my response from them here
Basically it's trying to pull a file that no longer exists for some reason (it wants to use the old main menu background art despite it being replaced) i've seen similar bugs before where it's for some reason trying to grab files or displaying images sometimes that haven't been used in an extremely long time.
deleting the game (and any other stray copies you might have) and reinstalling it entirely seems to work. it's not an issue with entirely fresh installs, though, and it's not an error i can replicate on my end either
If deleting the cache and reinstalling it isn't working you might wanna try grabbing it through steam instead since i feel like it's an issue with the way the itch app is installing updates.
