OutOfMemory crash while scanning files on F-Droid/FOSS version

[buttercookie42]

Phone: Moto G4 Play with Android 6.0.1 and 2 GB RAM

Installed Simple-Gallery 6.27.2 and made only the following settings changes:

1. Exclude both internal and external SD card root folders.
2. Manually included one folder on my external SD card, which has a substantial number of images spread across a number of folders.
3. Turn on sub-folder grouping.
4. (Force a folder re-scan.)

Result: Eventually, Simple-Gallery crashes with an OOM error (see attached log). gallery-394-oom.log

After switching back and forth between both versions, it looks like only the F-Droid (foss-release) version is affected – the proprietary-release seems to work fine.

guess it happens on proprietary too if you give the app the All Files access

For me crashes on latest version, while playing videos (taken by camera) and browsing through them, on latest version. Oneplus 7, no physical sdcard, android 12, plenty of ram

Using folder view Group direct subfolders: off

It didn't crash on previous versions. I can easilly reproduce by playing videos, and swiping to next video while playing, several times

Caught the errors in logcat:
