Getting this error"A simulation error has occurred. Would you like to run the Convergence Assistant to attempt to resolve this problem automatically?

I made my design using multisim. All I have to do is to give input and turn on the segment based on the signal.

My truth table is given below if anyone need to test. Its a common anode truth table.

I don't know what's wrong here. Why it is not working?
