There looks to be something wrong with schematic. In breadboard 24V is shorted to ground:
clicking on a ground connection shows a short to the 24V pin. If I then switch to schematic and do Routing->Select all traces then hit the delete key to delete all the traces
breadboard works correctly (indicating there is a short in schematic somewhere)
here ground no longer shorts to 24V indicating that the short was coming from schematic view somewhere. Looking at schematic after deleting all connections indicates there are non connections in breadboard on the base and collector of Q9:
switching to breadboard there is a failed connection in breadboard:
the rest of the trace should also be lighting up yellow when the q9 collector is clicked and it is not indicating there isn’t a connection there. Same with the base, the strip at the base lights but the wire after it does not when it should indicating no connection:
deleting and re running the two wires clears the problem:
with that done schematic routes correctly as well I used a ground net to simplify the wiring:
