Alright, it sounds like our devices are about the same age and the same OS version. I suppose it could be the different brand of android device, but there's nothing we can really do about that. I've been trying pretty much everything I can think of to replicate the error, but I can't manage to get any errors when opening the game on my end, which is odd if you've been able to play other RPG Maker MV games with JOIPlay. I also can't really find any similar bugs being reported for JOIPlay to give me an idea on what to try, though the error you are getting implies that the game is trying to read something that doesn't exist, so it could be some sort of read/write issue, maybe? These are mostly shots in the dark here, but a few more things you could try:

 What version of JOIPlay do you have downloaded? You can check by hitting the three dots in the top right in the app and clicking about. If yours is very out of date, that could be causing issues. The most recent version should be 1.20.023-patreon.

• When you added the game to JOIPlay, did you extract the game from it's zip file first, or did you add the game with "Import Archive File." I believe extracting the game first would be more likely to work.
• Does your JOIPlay app have permission to access Music, Audio, Photos, and Videos? It shouldn't even let you run the app if it doesn't, but it's something you could check.
• You could also try moving the game folder somewhere else on your phone. I ran mine from the download folder in my internal storage. If you are trying through an SD card it's possible that could cause some issues.
• And just to double check on something, when you tried the web version of the game, that one was opened with an index.html file, right? There is no .exe in the web version, so you would have needed to use the .html file to test that one out.

 Maybe one of those things will work. Sorry I'm not able to be more helpful here.
