Im trying to connect the resistor here, and I tried the electrical library, and I got a resistor from it, but when I tried to connect it, the plus generator and IGBT could not connect with it. After that, I tried to use the Simscap library, and I chose RLCSereirs, but I also could not connect, so what can I do

The input g is a Simulink control input. It is not possible to connect a resistor (physical block) to Simulink connections. If you need to model the gate driver I suggest to use the Simscape technology. Check the N-Channel IGBT block which has an electrical gate terminal:

I hope this helps.
