i followed the pictures describes on how to setup a custom location and i also enabled the storage permission but unfortunately, Cryptomator keeps stopping when adding local storage sd card. please help!
Hey and welcome in the community 
!
Can you please enable debug mode, reproduce the problem and send us the log?
How do I enable debug mode on Android?
Thanks!
Sir SailReal thank you for taking the time to read my post and also for the quick response. 
I already sent the log files. Thank you again and God bless!
Thanks for your log file!
The error message looks pretty strange 
While requesting a takePersistableUriPermission we get a SecurityException that no persistable permisson grants found for that path:
Caused by: java.lang.SecurityException: No persistable permission grants found for UID 10222 and Uri 0 @ content://com.android.externalstorage.documents/tree/6331-3639:
Do you use other apps that access your SD card that have no problems doing so?
Yes sir.most of them, such as vlc when browsing movies into my sd card. Google play music. etc.
Can you please test the following:
- What happens when you create a new “Custom locations” but select the internal storage instead of the SD card?
- What happens when you select the “Default storage”?
Does the app crashes in both cases?
1.The app crashes when creating a new location using internal storage.
- Creating a vault using the default Storage works just fine.
Below is the attached GIF file when testing the 2 questions
