This error is certainly related with your device app permission.
The file storage permission is enabled, just like I meant before. I used another device just of recent, there was a request to allow Electrum to allow camera and media, I clicked on 'allow', but the same error occured after I allowed it. Which means it is not by default like I meant before, but I checked the media permission, and it was set on allowed, I allowed it before. When I first saw the error, I checked it and it was set on 'allow'.
For reference, the error will be different if you didn't grant it media storage permission, so the issue must be something else.
