Release with the issue: version 1.3.6

Last working release (if known): N/A

Browser and Operating System: Google chrome on Windows 11. Edge gives the same results.

Description of problem: When I try to use a variable in the yaml configuration, the card dissapears from the preview and from the main view. I'm using the following code:

type: custom:config-template-card
variables:
  - '''RDCLAK5uy_loc3QkpRI5iaLbS_laJf0_OwzvPeAYrYc'''
entities:
  - switch.home
card:
  type: button
  entity: sensor.ytube_music_player_extra
  primary: |
    {{ state_attr('sensor.ytube_music_player_extra', 'search')[0].title }}
  tap_action:
    action: url
    url_path: https://music.youtube.com/playlist?list="${ vars[0] }"

Javascript errors shown in the web inspector (if applicable):
