I've installed TYPO3 version 9.5.5 and Tool backend error when I click Site configuration ( Site Configuration -> Add new configuraton for this site).

Error: Core: Exception handler (WEB): Uncaught TYPO3 Exception: #1256475113: The argument "parameters" was registered with type "array", but is of type "string" in view helper "TYPO3\CMS\Fluid\ViewHelpers\Be\UriViewHelper". | InvalidArgumentException thrown in file /usr/share/nginx/typo3_src-9.5.5/vendor/typo3fluid/fluid/src/Core/ViewHelper/AbstractViewHelper.php in line 356.

Maybe there is an error in your site configuration file. Try to remove the complete site configuration.

Look at these locations in your installation: /config/sites/YOUR_SITENAME/config.yaml (composer installation) /typo3conf/sites/YOUR_SITENAME/config.yaml (non composer installation)
