New Redmi 3 - 6.3.31 - Selecting Sd Card Not Working - Documents Application Crashes

[nouwak]

When I try to edit anything on SD card in some apps like File Manager or AirDroid, a panel about selecting SD card location appears.

As described in thread "Fix can't write/delete files on SD card (No Root Required)" on "en.miui.com" (sorry, can't post links) I enabled Documents application, but it only appears for split second and disappears.

I managed to get some logs, I attached them below. The main reason seems to be this exception:

04-03 23:16:09.867 23263-23263/com.android.documentsui E/AndroidRuntime: FATAL EXCEPTION: main
                                                                         Process: com.android.documentsui, PID: 23263
                                                                         java.lang.RuntimeException: Unable to start activity ComponentInfo{com.android.documentsui/com.android.documentsui.DocumentsActivity}: java.lang.RuntimeException: A TaskDescription's primary color should be opaque

Seems like some sort of GUI error. How can I make this application work to enable storing data on SD card?

Third party file manager applications will have to be granted read/write permission. If your device is rooted you can easily grant the permission.

Please, give more detail how to do it. I have btsync app that uses documents to select folder on sdcard.
