StorageAnalyzer slows system responsiveness after opening heavily populated media folders

[dgw]

Describe the bug
System becomes slow or unresponsive after StorageAnalyzer has been used to view a folder containing many (thousands) media files.

To Reproduce
Steps to reproduce the behavior:

1. Place 5-10 thousand (or more) media files into a single folder, e.g. /storage/emulated/0/Pictures/TestFolder
   • Optionally add a .nomedia file to this folder — I am not sure yet if this influences the behavior
2. Scan device with StorageAnalyzer
3. Browse the StorageAnalyzer results; system responsiveness should still be normal
4. Enter the test folder containing thousands of media files
5. Scrolling may or may not work; SD Maid SE should now be slow to react to Back button presses or other input
6. When I have been able to get StorageAnalyzer to back out of the problematic folder, system responsiveness has not recovered, as if some background task(s) spawned by opening the folder stay(s) running

Expected behavior
Regardless of how many files are in a given folder, browsing StorageAnalyzer results should remain responsive.

Smartphone (please complete the following information):

• Device: ASUS ROG Phone 3 and OnePlus Pad
• OS: Android 12 and OxygenOS 14 (yes, it's just skinned Android)
• Root status: No
• SD Maid 2/SE version: 0.24.0-beta0

Debug log
I will be happy to add this later, if needed; it takes quite a while to scan my devices

Screenshots/Video
As above, happy to add if needed.

Additional context
Generally I end up restarting the whole device to get responsiveness back. I can usually do so through the normal menus, with patience, but occasionally it has been bad enough that I considered just holding the power button to force shutdown.
