Fluid-based Page Module crashes with 2 language variants
100%
Description
With two language variants and active fluid based page module, this is not displayed correctly. When clicking on any page in the backend, the error message shown in the screenshot is displayed and the module cannot be used.
Return value of TYPO3\CMS\Backend\ViewHelpers\LanguageColumnViewHelper::render() must be an instance of TYPO3\CMS\Backend\View\BackendLayout\Grid\GridColumn, null returned
Tested under 10.4.3

I can confirm this problem.
It also exists if more than two languages exists.
The only way to "fix" the problem is currently to disable the fluid based page module feature.

Just to add some details (TYPO3 10.4.6 composer)
Steps to reproduce¶
1. Enable Fluid-based Page Module
2. Create a page inside a site with multiple languages
3. Apply a BE layout using colCount = 0 and rowCount = 0
4. Open the page in page module and switch from "Columns" to "Languages" using the action-menu (&SET[function]=2)
I alway apply an "empty" BE layout to e.g. sysfolders, external links, shortcuts etc. to prevent users from creating content elements.
