SingletonLock Chrome error?

I've been getting this error a lot lately, and therefore not able to watch any of the Discovery network channels (HGTV, Animal Planet, etc.) using TVE. Sometimes it works by deleting the three Singleton files in the "/mnt/data/channels-dvr/data/chromedata/Spectrum" folder, and then rescanning, but usually not. Any idea what's going on and any permanent fix? (Using Channels Server on a Raspberry Pi 4 btw, v 2024.03.22.1726.)
