What is the way to overcome procrastination in performing the prayer on time, knowing that waking up late is due to fatigue?

It is not permissible to sleep after the time for prayer has begun if it is highly probable that one will not wake up until after the prayer's time has expired. However, if one is certain to wake up before the prayer's time expires, it is permissible, though disliked. It is permissible to sleep before the prayer's time begins. To avoid procrastination in performing prayer, one should recall the danger of neglecting it, as it is a major sin, be mindful of Allah, and realize the virtue of hastening to good deeds, as Allah the Almighty says: "And hasten to forgiveness from your Lord and a Garden as wide as the heavens and earth, prepared for the righteous." (Quran 3:133). One should also seek Allah's help and supplicate. It is not permissible to delay the Isha prayer until after one-third or half of the night.
