[BUG] Auto-backup interval setting does not take effect

I've noticed a long-standing issue where adjusting the auto-backup interval setting does not actually work. I believe this is a very old bug, as I've been experiencing it since I first started using the player back in July 2024 (2024.7). When I change the auto-backup interval time, the setting seems to be completely ignored. Furthermore, the actual backups that get generated don't follow any obvious schedule or pattern—the time gaps between them seem completely irregular and strange. This issue exists on both the Windows and Android clients. My versions are: windows: v6.0.6 android: v6.0.6 The screenshots are below.
