NC 13.0.1 - News app prevents the Files/Gallery app from working correctly

Hi Nextclouders,
after I’ve successfully migrated Nextcloud from 12.0.6 to 13.0.1 and the latest apps, I realized that the News app seems to negatively influence the functionality of the Files or Gallery app, once it has been activated.
Instead of showing a picture in the Gallery when you click on it, a dialog to download it or open it with an external application is shown. I tried to identify the root cause of the problem but without success until now.
I’ve also opened an issue ticket for the News app (https://github.com/nextcloud/news/issues/279) where I’ve provided some screen shots and log messages. Now I wonder if the problem is really caused by the News App or it it is possible that other reasons could exist which causes the described problem. Every hint is appreciated!
