That’s a different issue.
How invested are you in your TVH setup currently?
If you’re able, I’d recommend:
sudo systemctl stop tvheadend
rm -rf /home/osmc/.hts
sudo apt-get remove --purge armv7-tvheadend-app-osmc
sudo apt-get install armv7-tvheadend-app-osmc
This will remove everything. And then following the on screen instructions when you log in to the web interface.
Cheers
