Level Object value is lost when a new level is loaded using the same BP

First discovered this on Linux in //UE5/Main. In the repro, you play from level 2; if you opened Level 1 and played from there, the same outcome would occur.

PIE: Warning: TravelFailure: ClientTravelFailure, Reason for Failure: 'Failed to load package '/Game/ThirdPersonBP/Maps/UEDPIE_0_Level1''. Shutting down PIE.

1. Create a new third person project or open an existing project
2. Create a second level
   • Name it something you can identify easily; I used: Level1 & Level2
   • Optional: add something to the level that can help distinguish between the two levels
3. Open Level 1
4. In the content browser, right click, create a new BP Actor, and open it
   • Name it Door_BP
5. Within the Door_BP do the following:
   1. Add a box collision to the actor under the components panel
   2. Click the box collision and in the details panel scroll to the bottom and add a OnOverlap Event
   3. Click the box collision again and set Hidden In Game to false
   4. Drag out from the OverLap Event and search for Open Level (by Object Reference)
   5. Right click the Level input node and promote to variable
   6. In the variables panel, make Level public by clicking the Eyeball to the right of the word World
   7. Compile and save the BP
6. Drag in Door_BP into the level and within the details panel, set Level to Level2
7. Save the current level (Level 1) and open up Level 2
8. Drag in Door_BP into the level and within the details panel, set Level to Level1
9. Save the current level and PIE
10. Move the character into the box
    • Level1 opens (check logs to confirm)
11. Move the character into the box

Expected Results:
Level2 opens

Actual Results:
PIE will close immediately. If the game was launched, the game does not crash, just closes.
