PickiT: Crash for some images

Describe the bug

After upgrading to PickIt 2.0.3 we implemented the method pickiT.isUnknownProvider(uri, Build.VERSION.SDK_INT). For some images, the program crash unexpectedly.

Describe the bug

We have this line where it crash:

if(pickiT.isUnknownProvider(uri, Build.VERSION.SDK_INT)  || !pickiT.wasLocalFileSelected(uri)) {
        result.error("IS_REMOTE_FILE", "The selected file is remote and is not implemented yet", null);
      }

And for this file content://com.android.providers.media.documents/document/image%3A66 the program crash.
But NOT for this content://com.android.providers.media.documents/document/image%3A65

Both are local (I can see them without internet connection). And if I disable the pickiT.isUnknownProvider(uri, Build.VERSION.SDK_INT) it still crashing. Neither downgrading to previous pickit version.

We also upgraded sdk from 30 to 31.
