I’m running the same AntennaPod version and it continues to work well for me with zero crashes.

Assuming that all of your other apps are stable and you aren’t running low on storage the most straightforward approach would be to export the AntennaPod database, uninstall the app, reinstall the app, and import the database. (You could go through the process of troubleshooting exactly what’s going on with your current installation, but that’s probably not worth your time and trouble unless you enjoy that kind of challenge.)

The crash is due to a NullPointerException when the app tries to update media metadata — looks like the MediaSessionCompat object isn’t initialized properly during playback. This might be a bug in version 3.8.0.

Try downgrading to version 3.7.x from GitHub, and disabling Bluetooth playback temporarily might help reduce crashes until it’s fixed.

Thanks for you suggestion, I will try it next time but since the day I posted it’s working fine.

Thanks for having a look into the log. It’ weird but since the day I posted, I didn’t experience any more crashes. I don’t know what fixed it. I will try your suggestion it the crashed come back. Thanks again!
