There is no problem with the circuit.
What is the capacity of capacitor C1? Is it an energy storage capacitor?

CON_FG1_O is high, then the transistor S8050 is turned on, and the gate (G) of IRF7424 is grounded, so FG1 and CON_FG1 are turned on;
On the contrary, CON_FG1_O adds low level, then the transistor S8050 is disconnected, and the gate (G) of IRF7424 is left floating, so FG1 and CON_FG1 are disconnected.

This schematic has a serious problem.
