Minecraft not launching/when u hit play just says error or crashs

So basically when u go to hit play on mc it just crashes or sends and error report I've talked to many people and they've had the same problem but ever since the new launcher came out this has been an issue and the old launcher worked perfectly fine could always log in anything I've tried many ways to fix this problem such as uninstalling mc and reinstalling updating java to the newest version and updating forge to the newest version nothing has worked still had the same issue. This happened yesterday when it first dropped and I logged in hit play like I usually do didn't change or do anything and it crashed so I then tried a new version and it won't let me even get on the latest version being 1.11.2 no idea why but that has happened to many people hope it can be resolved.
