Crankshaft disc torn off, engine damage?

What about a Ford Tourneo Custom 2.2 TDCI 125 hp, BJ 2012 with 130t KM. The following thing happened: January 2023 the AGR valve was defective, was replaced cost point about 1000€ June 2023 broke down on the highway of the turbocharger and was replaced – because of spare parts lack I got the car back only in early October. Cost point 4000€ at the beginning of November then when I wanted to go off there was a loud bang in the engine room. Vehicle immediately drove up to the parking lot 1 meter since no warning lights went on. I noticed servo steering dead. Engine exhibited and looked. And saw the misere, the crankshaft belt disc was torn off at the vibration damper (rubber) . Since at the time I could not afford any more expensive repair (replacement parts were already at about 800€ since at the time only the originals of Ford were available. Car was then standing still 3 months. Then it was repaired and turned up now according to the workshop. Before the repair was to bring it to the lifting stage was not short and had not turned up the lift and then had to bring it back to normal.
