For help with an unselectable otg file

[misaka513205]

Hello,thank you very much for updating QuickPic Gallery.But I got some problem before changed a new phone.
With my new phone on Android 15,I cannot select my otg file in ”Included Folders“ interface,

so i cannot view my photos in "File Browsing" mode

I've seen this feature on other photo apps, so I think it's may not a problem with Android version.
This problem has been bothering me for days and I haven't found a good way to deal with it, so could you please help to look at the cause of the problem or even fix it?
Thank you so much!
