System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: Intel(R) Iris(R) Plus Graphics Intel 4.5.0 - Build 27.20.100.8681

Blender Version
Broken: version: 2.92.0 Beta, branch: master, commit date: 2021-01-24 07:38, hash: d3506c86da
Worked: I have not found a version that works as expected on this computer. I have tried 2.79, 2.8, 2.91

Short description of error
After a few minutes of using Blender, the window freezes. Windows does not detect that it is not responding, but Blender does not respond to any input, including clicking on the close button. All elements that are drawn by Blender remain as they were at the moment of the crash except if I resize the window smaller.

Exact steps for others to reproduce the error
I have not determined exact steps. It has occurred on multiple files doing multiple different tasks. As far as I can tell, there is no correlation between what I am working on or what task I am performing, and the error occurring.

Please open Blender's installation directory and double click on the blender_debug_log.cmd. This will start Blender in debug mode and create log files. Try to make Blender crash again. Once it crashes the Windows Explorer should open and show you up to two files, a debug log and the system information. Add them to your bug report via drag and drop. Please also upload the crash log located in C:\Users\[your username]\AppData\Local\Temp\[project name].crash.txt (or simply type %TEMP% into the path bar of the Windows Explorer).

I've used that command before and pasted the contents of the file that is created in the original message. I have also included the two files it creates in this message, but as I said in the title, Blender doesn't actually crash, so a crash file is not created. Instead Blender just stops updating the window or responding to input, and the only way to quit is to kill it using Task Manager. As a test I let it run for a while just to see if it would either resume updating or crash so that I could get an error that could be fixed, but it never did either of those.

I have figured out that it may be related to using Material Preview or Rendered mode. I left it running overnight in Solid mode and it never froze. I thought it had stopped working in both Wireframe mode and Solid mode before, but I can't seem to reproduce it in those modes, however within a few minutes of switching to Material Preview or Rendered mode, it freezes.

When it first happened, I saw that it might be a driver issue, so I installed the latest drivers from the manufacturer instead of using the ones provided by the OS, but the problem persists.

Does this happen when using --factory-startup? Are you using a particular file? If so could you share that file?

Yes it happens when using factory startup. It happens with any file I am working on.

Here are the log files from the factory startup.

@fantomx11 I would suggest you update your graphics driver as the first step. The current one can be downloaded from Intel's website .

Based in your description it's currently not possible to reproduce the issue or identify the cause. We would need precise steps and/or a minimal example project to investigate this. If this happens when in material preview, then this could potentially be related to #85287.

I am pretty sure I downloaded drivers from Intel's website, but the page you linked to does not look familiar to me, so I will download from there and try again. Also, I discovered today that it also happens if I am in solid mode, but turn off limit selection to visible. So far it hasn't stopped working in wireframe mode nor in solid mode with selection limited to visible (I have tried both the default solid mode, and setting color to texture).

Thank you for pointing me to the correct drivers. The ones I got earlier were apparently not the correct ones. The problem seems to have been solved.

Closing as this seems to have been solved with the newest drivers. Please open a new report if you encounter any other issues.
