Conjuring 4 Isaidub Patched Page

"Isa Dub" could be referring to a dubbed version, maybe a regional dubbing. In some countries, especially in Asia, movies are dubbed into local languages. Sometimes these dubs have errors or patches because of censorship or editing for local content. For example, in India, the Tamil language might have a dubbed version, and if parts of the movie were censored, a patch might be distributed. So "Isa Dub Patched" might mean a dubbed version of the movie, possibly with some changes or added content to fit local norms or censorship laws.
