Every time I try to load in the new snapshot, the game crashes out immediately after the Mojang splash screen appears. Every. Time. I have tried everything I can think of: reinstalling Minecraft, reinstalling Java, even deleting the entire .minecraft folder and starting fresh, but I keep getting the same crash message:
Unable to bootstrap data fixers
as well as
Something went wrong updating!
java.lang.NumberFormatException: For input string: "25:SHIFT"
I'm attaching the launcher log as well.
Thanks for the assistance.
