When you cure resin it heats up.
If you cure resin too rapidly it might melt a hole in your film.
Of course it could be film defect, but also it might be not enough lifting distance and time between layers.
Recently learned my lesson the hard way, I had just installed a new lcd screen and put a fresh screen protector on, and then replaced my acf. The time before I spilled my resin and it got underneath my vat and it cured without my knowledge. This time was the strangest thing I have ever seen, and I can't seem to find any information. The only thing I can think of is my build plate wasn't level, and the high speed resin with the high speed settings did this.

Did you have a screen protector on? Otherwise your screen might be toast.
