Reloading level takes too much time

Open Level takes too much time to load the same level (2-3 minutes?).

However the interesting part is.

  1. If I close the project and open it again, I use keyboard short cut to OpenLevel → Super fast.
  2. Moment I open blueprint/ put some debug breaks and the play in game and press key to open level ->Super slow.

Once I mess with any blue print → level load is so slow in editor. If I don’t open blueprint at all. Level loading is extremely fast → few seconds.

What is going on?
