Method 2: Through TWRP Recovery.

It has been reported that deleting the '.android_secure' folder on the external sdcard (eg. via twrp) fixes the issue. 

So you have to boot into TWRP recovery and then delete this '.android_secure' folder from there then reboot your device.

This will do the trick if this still not works then follow below method.

Within the app I managed to rename android_secure folder and now I can access from the bookmark page as it should normally.
To rename the folder I had to access /mnt/media_rw/77B8-1D11 instead of the not working /storage/77B8-1D11

after renaming android_secure all is working ok.
