Issues with Lychee Pro Slicer Crashing/Freezing

Hi all,

I'm having an isue with Lychee Pro (free 60day upgrade from Elegoo Saturn 4 Ultra).

Ever since day 1 of having the Lychee Pro slicer, I have not been able to slice ANY file using the 'Normal" slicing engine speed if I have any form of AA enabled. I have tried slicing even the most basic .stl's such as a single "ResinXP2-ValidationMatrix_verdikt" Base Validation Matrix. I can get it to work on the much smaller files if I do not enable AA/Grey Offset, but even with neither option enabled, I can't do a print much larger than the calibration prints.

I can get about 20-45% of my other prints to work using the slicing engine speed "Fast Slicing Beta", but again, if they are anything remotely substantial Lychee will just crash or freeze. On a few occasions an error comes up with something like "Slicing Engine Crahsed", but it appears to continue slicing, though with nothing visual on my monitor. I have left these to fully slice on 3 occasions, however once I try to print these files, quite literally nothing prints. My Saturn 4 Ultra acts as if there is a file to print, will try to print as normal, however it blacks out the entire screen for every single layer, hence nothing actually printing.

To work around this, I have been doing all the work in Lychee, then exporting the scene to Chitubox and slicing the file there, which works every single time without fail, and completes the slice significantly faster than Lychee has been. Issue is, I prefer Lychee in almost every way and would much rather use Lychee for the slicing as well.

I would like to point out that my partner is having THE EXACT SAME issues on her PC, so it isn't just limited to my PC. She has a slightly less powerful rig, but not by much.

YES, I have checked and I have ticked that checkbox regarding Lychee sometimes using onboard Graphics rather than the GPU (I'm pretty certain I don't have any onboard graphics anyway), and having it ticked or not had 0 noticable effect on the slicer itself.

I haven't been able to find anyone else with a similar problem through my reddit and google searching so I'm hoping someone out there has some idea's on a fix?
