Help -Errors in Proteus - reports saturation current Op-amp circuit

[leok_electronic]

Hi friends, I'm about to present my College Final Paper. I carried out this project but I'm not getting the result. Proteus reports that there is a saturation current but I can't get the source (on errors). I have 10 days to finish. can anybody help me? I will attach the Proteus.
ps: there is a lack of connection in one of the transistors but even turning it on, it doesn't work.

Class D Amplifier, 100w

Thanks my friends!!!

The idea of class D operation is that output transistors are fully turned On and fully shut Off. Partial turn-on causes the transistor to present unwanted resistance and waste power.

Make sure you apply sufficient bias current (or voltage) to cause full turn-On. Avoid making bias so great that you damage transistors (or mosfets).
