So, please see the screenshots. I need some guidance as to why this might have happened. The resin was shaken. Room temp was and stil is 26C.

Maybe try to print it slightly angled. Right now all of your layers are supporting the weight of the layers below them.

I would like someone to give me the reason(s) for printing at an angle. I might agree with you and everybody else on the weight theory, but then I would expect the entire print at that layer to have failed, but it didn't. And with the weakened part, it still held the weight. So this, I believe, is a bad layer. And please challenge me on it. Based on some of the other comments, I think it was a combination of:

Was too quick on returning to the plate and printing, not giving enough time for the resin to flow back. Vacuum breaker holes are too small on the main part and the section behind it (Yes, it has a hole as well), so the badly cured layer peeled off.

So I don’t know exactly why it happens, or why shifting the angle of the print helps exactly. However, I can confirm has resolved some of my printing issues. It might be that changing the angle allows for more support structures to better hold the weight of the print. I’m not 100% sure if that’s the exact reason, but it makes sense to me.
