Strange issue, looks like SMG CU trouble?

[Kislik]

driving round the ring, made 2 laps to warm tires and than 2 fast laps and started 3rd. Than in one corner engine stopped, SMG light went on, brake sesnsor on, dsc of. Zero RPM. went to neutral in the smg, than back. engine on, errors still there but works. little later same again, always in right corner.

stopped the car, switched of, started. no errors. went back on track and again and again in right corners. slowly finished the lap with errors on. went to garage, engine ECU checked and ok, smg tested clutch adjusted but not possible to read anything. error still present on dashboard even after multiple starts ... leaved the garage just to go around, lights of, no more sign of error. drove it back home over 500km with not a single issue....

any help? see the video how it looked
