Trouble with cr-10s pro v2

Hello,
I have a CR-10S V2, and recently it started giving problems while printing, first I tried to do the auto leveling but it plunged hard into the bed then, after I manually adjusted the leveling and put the model to print, it started to print in mid-air then it started to print in mid-air, can you suggest some fix for this issue.

Find the g code reset script… run that. Should fix.
