Is watching pornography to help one's wife complete the marital act and break the barrier of fear considered a sin that prevents the acceptance of repentance and necessitates repeating the fast?

Watching what Allah has forbidden is of no benefit; rather, sins bring loss and misery. Seeking Allah's help, asking specialists, and consulting wise people will benefit the servant. The questioner's feeling of guilt is a sign of goodness, and Allah accepts repentance with its conditions. Shame from sin should motivate one to strive in good deeds. Fear of repeating a mistake is a trick of Satan, and the believer does not despair. The questioner should hasten to repent, have a good opinion of Allah, and frequently perform good deeds. Looking at forbidden things without the emission of semen does not invalidate the fast, but it diminishes the reward.
