When I try to download it on the app, it gives the error "an error has occurred during installation rar: an entry cannot be decompressed (Bare Backstreets_Data/sharedassets0.assets.resS)

Same over here

Hi Jesus! Do you have winrar installed by chance?

Like a .zip file, .rar is just a compression format. You can open it for free using https://www.win-rar.com/predownload.html?&L=0
