# Why render stops in save step in Blender?

i recently meet a wired problem, i am batch rendering image in blender , 98% of them work normally , that is render and save without any problem, but some image render will freeze in the save process

Look the screenshot , other image render ends within 2 mins, but some image render will freeze , i have to press Ctrl+C to terminate the freeze stage so the rendering can go on , i really dont know why

Here is the render part of my codes , and everything is based on standard , but sometimes image will freeze in render save step!!

img_path="D:\example"
bpy.context.scene.render.filepath = img_path
bpy.ops.render.render(write_still=True)


(i really wonder it is the BUG of Blender , if no efficient solution, i have to use multiprocess and pyclick to overcome this problem....,and i usually left the machine to render all day long , if one step freeze , it can cause super huge huge wastage !!!time and money!for example , today i lose around 5 dollars from this problem.. )

• Have you accidentally clicked into the command prompt? This would activate the QuickEdit-mode and pause the application (similar to T74995). Mar 21 '20 at 17:07
