Export fails

[bege10]

Description of the issue

Export fails. The backup folder contains the index folder and sharedpreferences.dat The logcat shows missing access permission. Syncthing-Fork has permission to access all files and root permission. Syncing works flawlessly.

Reproduction Steps

This was normal behavior on my recent phone but a second try always worked. Now it constantly fails.

• App Version: 1.27.3.0
• Syncthing Version: v1.27.3
• Android Version: /e/OS-T-dev (based on LineageOS for microG, Android 13)
• Device manufacturer: Shiftphone
