(VBA) How to loop through a ShapeRange with deleted elements?

Ok, I must be losing memory or something, but what is the correct way to loop through a ShapeRange that changes over time? As an example I have something like this (in pseudocode):

Tag:
For Each S In SR.Shapes.All

  For Each T In SR.Shapes.All
    If S compared to T is something Then
      T.Delete
      Goto Tag

    End If
  Next T
Next S

And no matter what I try:

  • Find the index and do SR.Remove
  • Check if the shapes exist before further actions
  • Use a temp Range from which the shapes are removed and then reapplied to the current Range
  • More stuff I already forgot

it throws an error at some point that the shapes are no longer there. Basically what I want to do here is remove overlapping shapes in the same ShapeRange with specific parameters.

Any suggestions?
