Hey all, I have been using LightBurn for about one year on my PC and never had problems. PC: i9-13900KS running on Z790 Formula. Approx 3 months ago I have started getting crashes of Ligthburn either during working or even during cutting with laser. I have tried to reinstall my PC and test all components (OCCT burning test passed, IPDT passed). I get the crashes even on brand new W11 install with just integrated graphics in i9 (RTX4090 left on the table for sure). The easiest way how to simulate crashes is just make few curves and then copy/paste them many times. After all the testing it seems to me the crashees might be related with last bios updates for i9-13900KS (Intel stopped using of AVX512 etc.). Does anybody have also 13900KS running on last bios and with working Lightburn pls? It could save me much time with trying different things. Sample file for CTRL+C/V attached
