Short description of error
Blender crashes when using F3 (Edit->Menu Search) while no active object in scene.
It happens form time to time, I don't really understand if this is persistent issue or something on my side.

Exact steps for others to reproduce the error

Open default Blender scene
Delete all objects or select cube and delete (basically we want to have no any active object in scene)
Press F3
Blender crashes

There was a bug #83829 that caused crashes but it should've been fixed in the build you're using.

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 by clicking on the upload button as shown in the screenshot below or 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).

@DotBow Thank you for the files. From the stack trace I suspect that this is triggered by one of your enabled add-ons. Could you please go through them one by one and check after which one it starts to crash?

@DotBow @EchoDot Could you please open Blender's installation directory and double click on the blender_factory_startup.cmd. This will start Blender with temporary factory default settings. Does it still crash?

I can't reproduce this in the referenced version or the current master.

@DotBow Apologies, I must have misread your report when you initially posted this. I can reproduce the issue and this was introduced by ad7682ffdb. It needs to check if the ob is NULL before calling the function or there needs to be a check in BKE_modifiers_is_deformed_by_armature if the input is NULL.
