[2.0.21] Crash placing parametrized blueprint with multiple parameters (FillBlueprintParametersGui::confirm())

The game can crash when using a certain sequence placing a parametrized blueprint that has multiple parameters.

To reproduce:
  • Start a new game with default parameters
  • Open the blueprint library, select a saved parametrized blueprint
  • Place the blueprint, this opens the configuration dialog
  • While dialog is open, double click outside the configuration GUI: this moves the location of the blueprint under configuration, and opens a second configuration GUI (If the second configuration dialog is moved, we can see the previous one below)
  • Either cancel the second dialog or validate the configuration, this does not seem to matter much.
  • If the first configuration dialog is validated, the game crashes.
If I cancel the 'zombie' configuration dialog instead of validating (either with Escape or close button), the game recovers fine.
If I try to change the configuration in the zombie dialog, the game also crashes.

Attached is the blueprint I've used to reproduce the issue, but I suspect this may happen with any parametrized blueprint that has multiple parameters (a single parameter blueprint does not seem affected).
