Hello, @samc99us , thank you for you report. We will try to fix in some next release. Issue created under SPE-2298, thank you, have a nice day

In case relevant or perhaps it helps someone in the future- I was trying to slice 25 parts on a single plate for upgrading my MK3S+ to MK4 (Printing them on my additional MK4 is nearly twice the speed - 22h vs 36h using pre-sliced MK3 gcodes) Anyway, after about 6 parts, the slicer would crash when trying to slice.

My work-around was to lay out the parts, make them all disabled/not printable. Enable "Background Processing" under Configuration->Preferences and then enable one part at a time while waiting for each part to finish slicing before enabling the next. Perhaps worth exploring the multithreading or GPU hooks?

This is a top of the line desktop basically so horsepower is not an issue. 32core i9 w/196Gb DDR5 Nvidia 4090 etc. Latest drivers, Win 11 Enterprise w/ 274 slicer and updated profiles. I don't mean to piggyback on this report so if my findings are different / unrelated please let me know and I will open a new report with requested info.

This crashes on my computer as well.

Should be fixed in 2.8.0-beta1. Closing.
