Got a new resin 3d printer: why am I getting holes?

Got an anycubic resin printer and I'm using their high speed resin (because it was bundled for free), and i tried to send a file using the high speed setting.

After the print it was seemed to be ok, then after i left in a bath of ethanol (IPA can't be found in stores in my country) i got all those holes.

What's the problem?

A slicer problem? The ethanol bath? The high speed resin that's not good?

They look like air bubbles to me, but it is weird they only come out after the bath. Could be they were already inside, but only covered by a thin wall of resin.
I usually use Isopropanol for bath not Ethanol, so I am not sure how your resin reacts with that. The bath should also be rather short, like 1min or something.
A few things to try:
If you are shaking your resin before print, then give it like 10 minutes after you pour it into the vat, so all bubbles come out and pop
lower the print speed
add wait times between the end of lowering the plate and light on
try to hollow out the model if possible, so there is less printing volume
