Short description of error
There is no error. Blender just crashes with no error.

Ok so here is what happened : I was working on a project for 2 days. It had around 3500 frames to render so i let it render at night while im asleep. last night while it was rendering someone saw the pc and thought i forgot to shut it down so they shut it down while it was rendering. Luckily, I was rendering the animation in Pictures so i could avoid accidents like this and continue rendering from where it was last, which in this case was frame 552. So today I fixed every problem that was caused by this accident and decided to let the rendering continue. I put the starting frame on 553 and press render animation. Suddenly blender completely crashes without any report or error. It just closes. Tried some stuff to figure out what the problem is and learned that the only thing that is causing this problem is the motion blur. when ever i turn it off the rendering works perfectly fine. another interesting thing here is that the rest of the rendering works with motion blur which basically means the whole problem is with this single frame. I tried rendering the frame 554 and some more and they all worked fine. the only frame that makes blender crash is 553. I checked the tasks with people with similar issues but none of the solutions there helped me.

Extra Info:
Blender version and build : 2.90.1, branch: master, commit date: 2020-09-23 06:43, hash: 3e85bb34d0, type: Release

Rendering Engine : Evee
Rendering Resolution : 1400 x 1080
Render samples : 40

Edit : Ok so I learned that There is a error but it appears only for a fraction of a second or so. I managed to use debugging to save its log and here it is :

So the error is EXCEPTION_ACCESS_VIOLATION

Update : So I just realized that the problem persists with certain frames of the animation. every 10 frames or so blender crashes and if u want to continue rendering you have to turn off motion blur for that 1 single frame every time. so yeah the problem only occurs in certain frames for some reason.
