SmartArt in Collabora Office 26.4: Crash when apply "Ungroup" to the diagram

Open the attached file in Collabora Office.

You should get a diagram, that is when you click on the yellow background, it gets a thick blue border with item "Edit Element" and you see cryptic shape names in the Navigator.

Right click on the yellow background and select "Ungroup" from this context menu => Crash.

I see the problem in Version: 26.04.0.1 (X86_64)
Build ID: 234d7514f33bcb302a21b6e7b7585965cf6a95ac
CPU threads: 32; OS: Windows 11 X86_64 (build 26200); UI render: Skia/Vulkan; VCL: win
Locale: de-DE (de_DE); UI: en-US
Calc: threaded

When a diagram is marked, the item "Ungroup" should be deactivated. Instead there should be a tool "Convert to Group" introduced.

Unghroup should be disabled everywhere, I added SlotStuff for that.
Instead there are (currently three) slots available in 'Customize', search for 'Diagram' called

• Convert Diagram to Group Object
• Edit Diagram (opens that small old dialog)
• Regenerate Diagram (forces a ReLayout, useful after load to compare ReplacementGraphic that will be shown if exists to ReLayout result).
  'Convert Diagram to Group Object' Is the one to get to a GroupPbject, the Ungroup will be available and works.

How are you able to trigger UnGroup slot? As mentioned, it should be deactivated everywhere...?

I click on the diagram in the yellow area, not on a shape. Now the diagram is selected. Then I right click, which opens the context menu. Using the context-menu key of the keyboard would open it as well. In the context menu I select item "Ungroup".

You can trigger "Ungroup" as well with Format > Group Shapes > Ungroup or with the shortcut Strg+Alt+Shift+G.
