Access violation when trying to access C.evaluated_depsgraph_get().view_layer_eval.depsgraph. Crash occurs when trying to list the members of view_layer_eval in an evaluated depsgraph. Looks like the member depsgraph is causing it. All member names not staring with d lists fine. When doing dir(C.evaluated_depsgraph_get().view_layer_eval) it tells me depsgraph is the only member starting with d in this namespace.

Exact steps for others to reproduce the error

Open interactive console and type the below. The last line should crash.

deg = C.evaluated_depsgraph_get()
deg.view_layer_eval.depsgraph

See attached redundant gif.
I even made a blend file. Just hit ctrl+space

Simply executing the following script in the text editor also shows the bug.

lang=python
import bpy
bpy.context.depsgraph.view_layer_eval.depsgraph

bpy.context no longer has depsgraph member

If I do steps to reproduce on evaluated_depsgraph_get() I get no crash.

Can you please check if this is still an issue in latest build?

Yeah. Type in console:

deg = C.evaluated_depsgraph_get()

deg.view_layer_eval.depsgraph  <- crash on hitting Enter

I don't think there's anything useful in this particular location, just the crash accessing in itself was amusing back then.
