please check your "plugin.xml" whether the FileProvider is configured.
the same as the following:

 <provider
            android:name="io.github.pwlin.cordova.plugins.fileopener2.FileProvider"
            android:authorities="${applicationId}.opener.provider"
            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/opener_paths" />
        </provider>

And, if you have done, it still can not work, you may add a permission for adapt the high Sdk version.

<uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES" />

@senjoeson the user does not really have any control over plugin.xml since it is located in the plugin source (that comes from this repository) and not in the user project?

The issue in my case was that the provider tag was not present in AndroidManifest.xml at all. Manually replacing ${applicationId} with my app id in the code above and inserting it into platforms⁩/android⁩/app⁩/src⁩/main⁩/AndroidManifest.xml solved the problem for me.

@nip3o please check your cordova version to adpat the place of code. each version is diffrent configuration in the file "plugin.xml". please check out https://cordova.apache.org/
