Crashes every time path tracer is used!

Cannot for the life of me figure this out, have used MANY different settings, default materials and objects. Nothing works. Really is frustrating thinking yet again Twinmotion has solved all there previous crashes with new updates but hasn't done anything regarding stability. It's like you are hiring software engineers straight out of high school, this is ridiculous.

Asus Prime X570

TdrDelay seemed to fix it....for now. We will see. https://twinmotionhelp.epicgames.com/s/article/Video-Card-GPU-Crash-during-export-using-Path-Tracer-Long-computation-times-TDR

Neither TdrDelay or TderLevel tweaks helped for me ... removing all vegetation works a treat though - solid as a rock if you do that.

147mb (with skydome active) before vegetation removed - would only path trace at level 1 at 1920x1080 - crashed or locked up at level 2

137mb (with skydome active) after vegetation removed - rendered at 4k resolution - path trace at level 1 - in 2 mins 30 seconds.

Hopefully there will be a fix for this ASAP - good luck development team. Thanks for an amazing bit of software - if you get this path trace problem sorted it will be 'nirvana'.
