It is in the System Tray.
I clicked the Delete and Recreate and Channels Crashed and the log is full of the same errors.
If it helps going through the log it seems to have started after the update to v2019.10.11.2223.
When I click Delete and Recreate this is what is in the logs and Channels DVR crashes...
