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?
Ethanol should be fine to use as far as I know. Do the holes go all the way through? If so your screen might have dead spots. You can visually inspect the screen by setting it to do a test exposure without the resin tank on it to check.
Also obviously check that your tank doesn’t have any failed print bits stick to the sheet.
It’s probably under exposed then. Something like this and this will help you tune your slicer settings. You might need to play with other settings if you have other issues, but most of the time the exposure settings will be the problem with new resins.
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

visual inspection of test exposure is ok, and then the vat is brand new so the sheet was immaculate
Is this the first print you’ve done with it? Have you done any exposure calibration with this resin?
first print with the printer and first print with resin in my life
The manual didn’t mention the exposure calibration at all…
