$GLOBALS['TSFE']->tmpl->setup for settings call is deprecated since v12 and removed in v13

$GLOBALS['TSFE']->tmpl->setup['config.']['tx_fluidcomponents.']['settings.'] ?? []

Call for config.tx_fluidcomponents.settings which are registered in TypoSript Setup is not working in a TYPO3 v13 Instance.

See https://docs.typo3.org/c/typo3/cms-core/main/en-us/Changelog/12.1/Feature-98914-TypoScriptAsRequestAttribute.html

It seems, that the $GLOBALS['TSFE']->tmpl is removed with v13.
A shortterm fix could be using $GLOBALS['TSFE']->config or $GLOBALS['TYPO3_REQUEST']->getAttribute('frontend.controller')
