So around last month my dock decided to make my notification badges blue and very large. I have no clue why. I’ve tried resetting the preferences, restoring them from time machine, restoring Dock.app from Time Machine and nothing works. Whatever caused this, also broke LaunchPad because the instant I try to open it, it just crashes, the dock quits and restarts, and it never appears. Any ideas?

First off, I would install any macOS software updates from the App Store in case it's a weird, uncommon bug with that version. (Current version is 10.12.2)
If your issue is not resolved after this, I would highly recommend testing in a new user account to determine whether or not the issue is system-wide. You could also boot into Safe Mode to see if the issue persists there. This would narrow down the list of possible culprits immensely!
If the issue appears to be user-based not system-wide, and still occurs in Safe Mode, I would then recommend rebuilding the the Launchpad database if you haven't tried this already.
When an issue does not occur in Safe Mode and has not resolved itself after restarting out of Safe Mode (yes, it can happen - albeit not often), it usually points to an issue with a kernel extension, third-party font, or a startup/login item. So at least if this is the case, we'll know where to start looking.
To rebuild the Launchpad Databases:
Note: Having a backup of your system is highly recommended as some of the tasks you will be performing delete user library data; not to mention you will be working with a couple of Terminal commands which if typed incorrectly can cause issues with your system.

I would suggest restarting your Mac at this point and then testing the issue. Keep in mind that the first time you open Launchpad it has to rebuild the databases it needs so it may take a bit longer to launch.
