Are u download it on phone?
well, try download it from externall browser like uc browser or else. U can refresh the download link if it start to fail.
But if the ur problem is file size when extracting i cant really help but make free spaces or just download it on pc and extract then transfer it on ur phone.
Then add it to joiplay.
Ah i see, i have this problem when play other games after updating my os.
Have u try using the newest version of joiplay? The one on play store are out dated they have problem update it.
Join joiplay discord server or find his (or her? Idk) patreon to get latest update, its free tho.
Btw im prefer vn stuff on mobile even when pc have better performance
