I started up Minecraft to see it automatically updated to the new Minecraft launcher, which I personally do not like compared to the version before this one. Another problem is that whenever I try to run mods it simply gives me an error message that reads, "An unexpected issue occurred and the game has crashed. We're sorry for the inconvenience." And it won't allow me to check the crash report. I can't find a place to switch back to the previous version of the launcher, which will hopefully fix my issue; please help. Thanks.
