Crash when calling SetVector2DParameter on a Niagara Parameter Collection

Crash when calling SetVector2DParameter on a Niagara Parameter Collection

Description

Crash when calling SetVector2DParameter on a Niagara Parameter Collection. The value for the SetVector2DParameter may or may not have to be changed in order for the crash to occur. 

Assertion failed: Param.GetSizeInBytes() == sizeof(T) [File:D:\build\++UE5\Sync\Engine\Plugins\FX\Niagara\Source\Niagara\Public\NiagaraParameterStore.h] [Line: 526]
Steps to Reproduce
  1. Create or open any project with Preview 2
  2. Create a Niagara Parameter Collection with a Vector2D property
    1. Right Click in Content Browser go to FX then Select Niagara Parameter Collection
    2. Open the collection then select the '+ Add Parameter' button on the right hand side
    3. Under Common select Vector2D
    4. Save then close the Collection
  3. Open the Level Blueprint then add an 'Event Begin Play' node
  4. From it create a 'Get Niagara Parameter Collection' node
  5. From the return value of the Collection node create a 'Set Vector2D Parameter' node
  6. Save then close the Level Blueprint
  7. Play in Editor

Expected Results:
PIE works without errors and the value of the Vector2D is updated or a warning for misuse is displayed.

Actual Results:
The Editor Crashes.
