Crash when trying to move the material result node #19

When I try to move a material result node the engine crashes, regardless of the material, whether it is an existing or a new one the problem occurs.

UnrealEditor_Restyle!SDefault_GraphNodeMaterialResult::MoveTo() [D:\build\U5M-Marketplace\Sync\LocalBuilds\PluginTemp\HostProject\Plugins\Restyle\Source\Restyle\Classes\Default\Nodes\Material\SDefault_GraphNodeMaterialResult.cpp:76]

Other user reported the same issue on v5.1, but i can not reproduce it.
(I've been trying to cause it with different features on different materials)

Bugged code is the same with Unreal Engine's one, so i assume that RootNode->Material->MaterialGraph is getting invalidated somewhere on the background and it isn't so obvious why

Can you tell me more about the state of editor when crash happens?

What version of UE you are working with?
Is any "Material Result" node movement causing crash? Or does it moves and at some point crash happens
Do you have some extra features enabled? (Material related)
When it does happen and when it doesn't? (Like you just opened new material graph, or you have been working with it for some time)

My unreal version is 5.1.1
Any move I make with the result node the engine crashes.
I believe I have, it's been a while since I changed anything related to the materials, So I'm not sure.
This problem happens every time, there was no time that it didn't happen.

At the current moment i can only recommend disabling this node, until i know more about this

Ok, I tested it on a new project but the problem still happens, so if it is some configuration that is causing this problem, it can only be some engine configuration, because no project configuration causes this problem, if I know any relevant details I'll let you know, thanks for your attention.

I get this too, only just started using the plugin. I'm on 5.1.1 on Windows 11. Here's what my graph looks like (I've since disabled the plugin):

As soon as I click the result node I get a crash. It throws a null reference exception here:

The file is Restyle\Source\Restyle\Classes\Default\Nodes\Material\SDefault_GraphNodeMaterialResult.cpp
