If the player has negative health, it tries to get the sprite from a negative index. If the player has 1 health, it will get the 2nd sprite in the array, because the first index is 0. I assume the first sprite in the array isn’t for when the player is dead at 0 health.

Change
HeartUI.sprite = HeartSprites[player.curHealth];
To
HeartUI.sprite = HeartSprites[Mathf.Max(0, player.curHealth - 1)];
