Since Q2’s symbol type is “QP”, the netlist annotates the instance as requiring a PNP transistor. Since you didn’t select a specific transistor, it becomes a default transistor, which is NPN. Using an NPN transistor for a PNP is a error which must be corrected before moving forward.
the solution is right click the transistor=>Selection Guide and actually pick one.
Maybe less-obvious error messages should be explained in help.
