Data export problem from tinydb in android 10

I have a problem with the application I have created for data logging. The application saves data in a tinydb and then exports it in csv. This works on all devices with Adroid lower than version 8, but not on Android 9 or 10.
How can I fix this, since I have devices with important data that needs to be extracted?
Is there a way to manually extract data from tinydb on devices?

How can we know what you did wrong without seeing your app? But I think maybe you are using a split text block. Insert your .aia.

Hello Edinson

This rather looks like the File Path permission change made by Google from Android 10, but you say the problem definitely occurs on Android 9 too?

It is correct it only gives me the error in android 10 but I already managed to find the file that the app generates only in a path within the android 10 system

Sorry for the bad explanation below I add the project
