Pure virtual function being called while application was running(GI's running == 1)

I am not sure what could have cause this.On project startup i get this error and after i click either ok or close the message it crashes meaning i cant even access any blueprints to remove logic and somehow figure out which is the faulty file or reference.I need of a way to at least stop the crashes because crashes have led to my project being corrupted in the past causing me to restart from a backup and losing days worth of development

Any help is appreciated!

Turns out deleting Binaries,Build,DerivedDataCache,Intermidiate and Saved folders solved it
