Resin prints pulling away from build platform
It's difficult to tell from the image, but one aspect of resin printing that you want to consider when placing a model is the cross-sectional area for each layer. You'll see prints that could be printed flat on an FFF printer being placed at an angle on a resin printer.

This orientation presents a smaller cross-section and thereby a smaller amount of force applied when the bed lifts and peels the model from the bottom of the vat.

If you have the ability within your slicer to scrub through the layers, observe the general area created by the slicer for each layer.

If you tilt the model even a few degrees from level, you'll reduce the forces involved.

It appears that you've used a "priming" layer on your bed, the initial layers of resin ostensibly provided to reduce the problem you're experiencing. That's a good start, but the rest of the model is generating enough peeling force to ruin the print.
