The built-in class "UMaterialEditingLibrary" provides various editor scripting functions related to creating and editing materials and material instances. One of these functions, UMaterialEditingLibrary::SetMaterialInstanceParent(), is meant to allow a script to change the parent of a UMaterialInstanceConstant. However, using this function often results in an immediate editor crash with some different callstacks (see attached), or in the rendering of a material with seemingly garbage attributes. The same happens if attempting to change the parent using the generic "Set Editor Property" node from the "Kismet System Library".
Note that changing the parent of a material instance through the Editor UI does not crash. This is because the Material Instance Editor (FMaterialInstanceEditor) uses a "preview material" (UMaterialEditorInstanceConstant) internally, and changes to its parent result in the call of UMaterialEditorInstanceConstant::PostEditChangeProperty(). This function does everything that is required to properly update the parent, while UMaterialEditingLibrary::SetMaterialInstanceParent() and UMaterialInstance::PostEditChangeProperty() fail to accomplish that.
Note: This issue is related to [Link Removed]. But now there is a built-in specialized editor-scripting function for the task of changing a material instance's parent, and even that function causes a crash, which is a worst outcome than the one described there.
This if from ticket:

(Which is too long to fit into the URL field)
1. Create material assets
1.1. Create a new Material "Mat_A" (right-click Content Browser – Create Basic Asset – Material)
1.2. Create a new Material "Mat_B" (right-click Content Browser – Create Basic Asset – Material)
1.3. Create a new Material Instance "MI" (right-click Content Browser – Create Advanced Asset – Material – Material Instance)
1.4. Check that the "Parent" property on the newly created Material Instance is set to None
1.4.1. The editor may also crash later if the parent is initially Mat_A or Mat_B, but with less certainty
2. Create Editor Utility Widget
2.1. Add two buttons "Btn_A" and "Btn_B" to the widget
2.2. On each "On Clicked" event, call node "Set Material Instance Parent" from the "Material Editing Library"
2.3. On the event for "Btn_A", set "Instance" to "MI" and "New Parent" to "Mat_A"
2.4. On the event for "Btn_B", set "Instance" to "MI" and "New Parent" to "Mat_B"
2.5. Compile and save
3. Use the material instance on the current level
3.1. Place a Cube actor on the current level
3.2. Drag "MI" to the cube (or set it on the cube's Details Panel under "Materials – Element 0")
3.3. Save the level
4. Run the utility widget
4.1. Press each button until a crash occurs (example call stacks are attached).
4.1.1. The editor should crash on the first attempt or on one of the first few swaps.
4.1.2. It is also possible that the cube starts being rendered with a garbled material (e.g. wildly varying emissive and other properties)

No public tracker found
Not a regression in terms of the new function mentioned in the ticket. But yes a regression in terms of the functionality as a whole, as noted in the related ticket mentioned.
