Steam Mysterious Derailment On Rapid Transit With Br1142 Talent 2 Md

The video speaks for itself: the second car derails for no reason at the exit of platform 1 in Leipzig-Connewitz.
I don't see any derailers and signal 61 N1 is green.

The service is the 2021 timetable: [S6][30min] Leipzig Messe - Geithain.

(Also, in the videos, the train's screens become unusable after restoring a backup, which I did to reproduce the derailment.

I think my progress on this service is toast.

 

Its been like that since it was released all them years ago.
