I attached the crash log for anybody who is so very nice to help me. After years I finally had the energy to post a crash log. It´s just so annoying when you hit render and blender crashes. Then I restart at the last frame rendered and everything works fine… it´s just not reliable. Maybe someone can shed some light into my brain
It seems your additional bought Physical-Starlight-Atmosphere addon is the culprit… ??

Or you are simply running out of VRAM. Well, that’s annoying. It would explain why it works after restart - Blender uses less VRAM when it starts and then it gets filled with stuff and unfortunately it doesn’t free up just by itself. The solution is to get a GPU with more VRAM if that’s the case. …or try command line rendering for your bigger scenes… …or try using tiles for large resolution renders.
