Description

When we set label_alt of a table to a field of type select then a PHP warning is raised:

Array to string conversion in typo3_src-12.4.15/typo3/sysext/backend/Classes/Utility/BackendUtility.php line 1543

This occurs since TYPO3 12.4.15, with older versions there doesn't seem to be a problem. I did the tests with PHP 8.2. I don't know if different PHP versions make any difference.

Steps to reproduce:

Add the following code in some EXT:xxxx/Configuration/TCA/Overrides/tt_content.php
```
$GLOBALS['TCA']['tt_content']['ctrl']['label_alt'] = 'header_layout';
```
Instead of header_layout you can use any field of type select to trigger the problem.
Clear the cache
Edit any existing content element
The warning should be triggered.

The warning is not triggered when creating a new record. If you create a new record you need to close the edit form and edit the record again.
Maybe the problem also occurs for other field types, I only tested select fields with renderType = 'selectSingle'

I can confirm this issue with a nested inline field.
