need help with decoding file error

so last night I was reading the book "The Wandering Inn" just fine, but today when I try to open the epub it shows a decoding file error. So I tried downloading another epub of TWI since I thought it might just be corrupted, but then every other epub of TWI I tried just shows the same error. Any way to fix this?

note: Epubs of other books work just fine its literally only for TWI
