At some point in time (about a week ago) something happened to my Motorola Moto Z2 Play / Android 8.0 that caused my base apps (actually -- just Contacts) to not have access to my media files (i.e. audio, photos etc.).

Examples:

• all my custom ringtones (i.e. based on my own media files) were reset to default sound,
• I cannot pick a photo for a contact because my contacts app keeps saying: "No pictures are available on the device".

While first situation is resolved. I see my custom ringtone files in the list and I can go through my contacts and assign them again. But second situation is not resolved. I see this error all the time and I cannot change any contact's photo.

This is verified as not a bug (tested three different contacts-like applications and all of them shows exactly the same message, when trying to change contact's photo). But still, it seems that problem is limited to contacts-related apps only. Other apps still has read and write access to my custom files.

For example: :

• (read) I can pick any photo or other custom file and attach it to an e-mail, send it as MMS or share it in any other way or
• (read) upload it to OneDrive or Google Drive etc. or
• (write) my Camera app is still able to make new photos and store them in "DCIM" or
• (write) my sound recorder is able to record sound and write audio files.

The only thing that has changed on my phone recently and that I suspect as the cause of above metioned situation was Android 7.1.2 --> Android 8.0.0 update.

Is there anything I can do (since replacing contacts app didn't resolve the situation) or check in this case? Or resetting the phone to factory defaults is the only option that I am left with?

Examples:

• all my custom ringtones (i.e. based on my own media files) were reset to default sound:
  • Contact apps reset custom ringtones for contacts to default one,
  • Alarms & Clock app reset custom alarm tone to default one,
  • SMS (Messages) app reset custom message notification tone to default one,
  • system-wide default notification tone (set by me to custom) was reset as well,
  • system-wide default ringtone (set by me to custom one) was reset,

EDIT: I have cleared cache and data of media app, as suggested in comment. It didn't help.
