ANR in MainActivity when handling multiple PopupWindow events during stress testing

[LuMeng425]

Describe the bug
The app encounters a recurring Application Not Responding (ANR) error in MainActivity. It appears the UI thread hangs while dispatching input events related to PopupWindow during high-frequency interactions.

To Reproduce
Steps to reproduce the behavior:

1. Open Amaze v3.11.1 on an Android 11 emulator.
2. Perform rapid UI interactions (random clicks and swipes) specifically around the main file list to trigger popup menus.
3. Continue the stress test for several hundred events.
4. The app will freeze.

Expected behavior
The app should handle rapid input events gracefully and the main thread should remain responsive even under stress.
