Cydia not installing after jailbrake

So i jailbroke my device (iphone6+) yesterday and i got everything to work i downloaded and installed a few tweaks and by accident i installed a tweak that wasnt compatible which made my cydia crash i put my phone on safe mode and removed all the tweaks all of a sudden my phone rebooted and removed cydia on its own after that i tried re-jailbreaking multiple times but whenver it says jailbreak is complete it wants to start installing cydia and respring it just remains like that never installs cydia and it never resprings Plz let me know if anyone knows how to fix this
