Need Help Un-Installing a Bad Tweak!
Are you sure it's a boot loop and not a respring loop? You say you "got out of it" suggests it's the latter. Cydia crashing means you're not in Safe Mode but rather in an unjailbroken state. Whilst tapping go in yalu102, hold volume up until the device resprings to try entering No Substrate Mode. From there you should be able to open Cydia.
