Reproduced 3/3 times, issue does not occur in //UE5/Release-5.0 - CL 20979098 Binary. Confirmed Regression.

It's only through the Details panel that this happens; Geometry Collection visibility can be toggled through blueprint events as expected. When GC is by itself, it resets visibility on PIE but it can still be toggled as expected. 

Steps to Reproduce
  1. Create a new Geometry Collection
  2. Create a new Actor BP
  3. Add the Geometry Collection to the BP as a component
  4. Highlight Geometry Collection in Component Panel
  5. In Detail Panel, set Rendering>Visible to False for Geometry Collection component
  6. Compile
  7. Add BP to level
  8. PIE

Actual Result: Geometry Collection component becomes visible while PIE, and stays visible even when user attempts to toggle visibility through Detail Panel

Expected Result: Geometry Collection component is not visible at start of PIE, and has appropriate visibility when toggled through Detail Panel
