I can't reproduce on Windows either.

If this also doesn't work with factory defaults, as @lichtwerk suggested, please open Blender's installation directory and double click on the blender_debug_gpu.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 by clicking on the upload button as shown in the screenshot below or via drag and drop. Please also upload the crash log [your project name].crash.txt located in C:\Users\[your username]\AppData\Local\Temp\ (or simply type %TEMP% into the path bar of the Windows Explorer).

Robert, Philipp.
Thank you for looking into this.

Previous version 2.90.1 did not crash.
blender-2.92.0-b5d310b569e0 does NOT crash with default factory settings

Here are the crash files generate after starting blender 2.92.0 with "blender_debug_gpu.cmd"

Should I disable all add-ons and re-enable them one by one to see which one would cause the crash or would there be another reason besides add-ons for blender to crash?

Cheers

@fredhopp Checking every add-on one by one is a good idea. Before you do that, could you please upload the crash log C:\Users\admin\AppData\Local\Temp\blender.crash.txt as well? This will likely tell us what went wrong.

Thanks Robert.
I was looking for it in my current user folder, I did not think of checking in the admin user folder.
Here it is.

@fredhopp Thank you for checking. Unfortunately, it does only show that it crashes in the walk navigation code. Please check if a particular add-on causes this. If it is one of the add-ons shipped with Blender we will try to fix this, if it is a third-party add-on then this would have to be reported to the developer / company of the add-on.

Also crashes for me with MacOS on beta b99faa0f56 and alpha bc090387ac with factory defaults and no add-ons but only after deleting the camera.

Thanks fiftysquid.
"after deleting the camera." When reading this I realized that I was doing the fly/walk without a camera, expecting it to walk/fly the perspective just like in previous versions of blender.
I can confirm that it does NOT crash with a camera but only with perspective.

@fiftysquid Thank you for that tip. Without a camera is indeed the case were it crashes.

In ED_view3d_cameracontrol_acquire it attempts to access v3d->camera->transflag without checking if camera is NULL.
