Exception in page layout using latest "master" branch

[sypets]

Using latest master with latest TYPO3 11.5 branch.

I initially reported this for the branch #148, but this can be reproduced with master.

Reproduce

Using latest installation base on TYPO3 core repo (without Composer) + EXT:styleguide.

Prepare:

1. Created "clean" installation (uninstalled previous wv_deepltranslate, DB update, cache flush etc.)
2. git cloned
3. Activated via Extension Manager, double checked DB update and flushed cache

Reproduce

1. Go to start page in page tree (with several lanagues)

Possible cause of error

<select class="form-select" name="createNewLanguage" data-global-event="change" data-action-navigate="$value">
                    <deepl:deeplTranslate context="{context}"/>
                    <f:for each="{deepl:deeplTranslate(context: '{context}')}" as="languageName" key="url">
                        <option value="{url}">{languageName}</option>
                    </f:for>

Viewhelper is called twice. The way it is used should cause problems because it returns an array.

Further investigation:

!!! The templates / partials for v10 are also parsed so this can result in problems in v11 !!!

When I make the following changes (just for investigating what's the problem), the exception is no longer displayed:

1. remove the line <deepl:deeplTranslate context="{context}"/> in Resources/Private/Backend/Partials/v10/PageLayout/LanguageColumns.html

2. remove the line <deepl:deeplTranslate context="{context}"/> in Resources/Private/Backend/Partials/PageLayout/LanguageColumns.html

Also, there is this: DeeplRecordsListController

. '<select class="form-select" name="createNewLanguage" data-global-event="change" data-action-navigate="$value">'
                            . $options
                        . '</select>'

When setting breakpoint in the ViewHelper, I can confirm it is called, creating the array mentioned above.

After the above changes, I can load the page but then get this exception when trying to create another language overlay for the page ("Create a new translation for the page"):

Shold be resolved with this: #143
I saw the problem, too, and changed implementation of correct Template in ext_typoscript_setup
