Custom card does not exist error on desktop only

Hi,

I use the vertical-stack-in-card custom card in my HomeAssistant. This works fine on my phone (Chrome browser), but on my desktop it does not load: "custom element doesn’t exist”-error. I have already updated Chrome to the latest version.

I am running HomeAssistant on Docker on my NAS. I copied the RAW text from the .JS file and placed this in the right directory (I use multiple custom cards and they all work, except this one). I have added the right rules to the Lovelace configuration. Again, it works properly on my phone, but not on my browser on my PC.

Any suggestions?

Thanks!
