L293d and extrnal powersupply issue !! Answered

My main problem here that i have a doubt that tinkercad can go somehow wrong ! In this connection that i think is right , the l293d burns beacuse enable pin has higher voltage than powersupply pin or vc2 . But in conncection the 9v battery is with vc2 not the enable and the multimeter shows that , is there any thing can be wrong ?? (Enable is connected to arduino directly to send pwm values )

You need to conect VSS to arduino +5v, +9v of battery to VS and you must combine the battery gnd and Arduino gnd pin.
