System Information
Operating system: Ubuntu 22.4
Graphics card: NVIDIA Corporation GA104M [GeForce RTX 3080 Mobile / Max-Q 8GB/16GB]

Blender Version
Broken: official 3.4
Worked: 3.3

Short description of error
While rendering an animation Cycles stops after a certain number of frames rendering. Everytime on a different frame. The render progress bar stays frozen. the interface can not be clicked anymore. I have to xkill. Simple scenes can be rendered though more complex ones as on the attachment cause this error. 3.3 can render same scenes without problems

Exact steps for others to reproduce the error
Render in cycles an animation.FROG_02.blend

I personally experienced an issue like this yesterday with Blender 3.5 (most up to date with master at the time of testing) and rendering a animation with OptiX using a RTX 3060 with driver 527.56 on Windows 11.

I also experienced this issue intermittently over the last few weeks, but I thought it was caused by some of my own personal changes to Cycles that I was testing at the time.

This issue is "hit or miss". Some times it occurs, other times it doesn't, and I'm not sure why. I continue running some tests and see if I can find anything useful.

I should clarify something first. The issue I'm experiencing is this: I'm rendering an animation and then Blender pauses and becomes unresponsive. It doesn't return to normal and I have to force close it.

I ran some tests and found this out:

Using really simple scenes makes it easier to reproduce the issue since frames get rendered really fast. And this issue usually appears at the start/end of a frame (I'm not actually sure which end it is, sorry)
This issue can be reproduced with CPU rendering and GPU render on different operating systems (I tested Windows and macOS, and the user who made this report tested Linux, assuming we're talking about the same issue)
When attaching Blender to a debugger, it seems thread 1 gets stuck around BLI_rw_mutex_lock (in source/blender/bf_blenlib/intern/threads.cc) when the issue occurs. This is the same on Windows and Mac. It usually reaches this function and gets stuck while calling other functions like BKE_image_acquire_renderresult and RE_AquireResultImage
I can reproduce the issue even while running Blender with the launch command -t 1.

I don't really know how to progress from here since I'm not particularly knowledgable in this area. But it seems this issue is related to changes made to the displaying of rendered images. It may have something to do with b132e3b3ce or something else. So I'll tag @brecht @fclem and @Jeroen-Bakker to see if they can have a look at it?

Here are my steps to reproduce the issue:

Change your Render In setting to Image Editor (Steps to change this setting are as follows: From the top of Blender select {nav Edit > Preferences}. In the Preferences window, go to the Interface tab and change {nav Editors > Temporary Editors > Render In} to Image Editor). I can only reproduce this issue if an image editor is open and set to Render result in the main Blender window and this is an easy way to ensure it happens.
Create a fast to render scene (I have been using Cycles as my render engine, I'm not sure if it impacts EEVEE).
Render a "long" animation (I set my frame count to 2000 to ensure the issue occurs).
At some point, Blender will freeze/stop responding. This is the issue.

And here is the scene I've personally been using for testing:
#103101 Render freezing during animation.blend

And here's a video demonstrating the issue on my computer:
