Everything runs like normal on DirectRT until a key is pressed for the last trial (same as previous trials that worked without problems). The screen seems frozen there and an error message says that technical issues were encountered during this session. please see TrackPerformance.txt. None of the data were not saved.

Below is what is said in TrackPerformance.txt. Can this be fixed? Thanks.
