View the Version history, there is sometimes a duplicate that makes the game crash instantly, instead, check if it's a dupe, if it is, download the same exact one that came first. The first one is mostly the dupe. If it still crashes, wait for another update or download the not very outdated other version that isn't a dupe. Roblox doesn't force you to update to the latest version instantly unless your version is too old. Hope this helped.
