Why is my editor super easy to gets stack?

Hey guys, i wonder why is my editor super easy to get stack?

I have this little project which worked just fine, and the editor worked smoothly.

While after today’s work, the editor just got super easy to stack even if i was just clicking on items in the world outliner to see details.

For example, i just launch the project and not even start the simulation. I just click on different items in the World Outliners for like 5 or 6 times of switching, the editor was stacked! And it had very high cost of memories. Similar,during the simulation, after i clicked on some item in t he World Outliner, the editor also got stack…

After i switched to another project with 4,27, the same problem disappeared. So i guess it was related with the project config…

Any help would be Great!

WIshes!
