I can open up roblox just fine except that when I join a game, a few seconds later, the game crashes, screen becomes fully black, except the the buttons, which I'm unable to press because my phone also crashed. At this point I can't even interact with anything, not even my phone, I cant exit the game. I press the off button on my phone and it takes a fill minute for it to actually power off. When I turn my phone on again, I get a pop-up saying: system ui not responding. Now I'm unable to play roblox, I very tried to fix with ways I read on Google but none worked and I dont have a computer to play on. Anyone knows how to fix this issue?
