Android Question B4x 10.70 Android asset subfolder

I am using the latest B4x version
I have changed the Targetsdkversion From 29 to 30
and I have 3 subfolders inside my Project Files Folder that hold some images

but it seems I cannot read those images in the subfolder anymore if I run under Targetsdk 30
in target sdk 29 it works fine

I read the images from that path

file:///android_asset/mycat/cat1/mainclassic.jpg

but it seems I cannot read from that subfolder anymore any idea why ?

Edit : it seems this case not only in Targetsdk 30 but in that b4x version 10.70
