if (NRF_PWM1->TASKS_SEQSTART[0])
NRF_PWM1->TASKS_STOP = 1;

This check will never be true, task registers are write-only.

Do this instead:

NRF_PWM1->TASKS_STOP = 1;
while(!NRF_PWM1->EVENTS_STOPPED){};

NRF_PWM1->PSEL.OUT[0]=(PWM_PSEL_OUT_CONNECT_Disconnected<<PWM_PSEL_OUT_CONNECT_Pos);
NRF_PWM1->PSEL.OUT[1]=(PWM_PSEL_OUT_CONNECT_Disconnected<<PWM_PSEL_OUT_CONNECT_Pos);
NRF_PWM1->PSEL.OUT[2]=(PWM_PSEL_OUT_CONNECT_Disconnected<<PWM_PSEL_OUT_CONNECT_Pos);
NRF_PWM1->PSEL.OUT[3]=(PWM_PSEL_OUT_CONNECT_Disconnected<<PWM_PSEL_OUT_CONNECT_Pos);

NRF_PWM1->ENABLE = (PWM_ENABLE_ENABLE_Disabled << PWM_ENABLE_ENABLE_Pos);
