Well shanr, it wasn’t what I thought. In fact I cannot find anything wrong with it and I can’t get it to crash. You could change the Render Tile Size to something like 32 * 32, or 64 * 64

300 *300 is a bit large for CPU renders and together with Denoising that consumes a lot of memory. (But not so much to induce any kind of crashing.)
Did various kinds of renders, but everything was always okay, so it seems that it’s not the file that is causing the problems.
BTW I do not have a fancy high-end PC or so. Mine is more than 8 years old, can’t even render on GPU;)
