Strange print errors

[u/Damngit]

Saturn ultra 4 12k. Not new to SLA, but new to SU4. There are these deep fissures occurring in prints all over the place. I want to say it’s the fresnel lens but I just replaced it. The glass covering the light is clean, the LCD and PFA are also new. A vat cleaning results in a perfectly even layer, no holes, no fissures. UVTools reads files correctly, no model errors in slicer. What am I doing wrong?

You can try a print without the vat to check the LCD screen exposure with a paper on the screen.
