NotSupportedError: Cannot define multiple custom elements with the same tag name

Configuration

Searched but didn’t find much info. From time to time I saw below on the log, does anyone know what’s wrong and how to fix it? I believe I am running the latest HA and rgb-light-card.

I have just updated HA to 2020.12.2 and have the more or less the same error but apparently with vertical stack in card.

Must to be something related to HACS…

Already an old topic, but today I saw the same error in my log file, but on another card.
Running the HA version 2021.12.9
