This happens in 9LTS if you use ExtensionManagementUtility::addModule() with 7LTS parameters. Instead of
'labels' => [ 'tabs_images' => [ 'tab' => 'EXT:someext/Resources/Public/Images/icon.svg', ], 'll_ref' => 'LLL:EXT: someext/Resources/Private/Language/locallang_mod.xml', ]
you need the 8LTS+ parameter type
'icon' => 'EXT: someext/Resources/Public/Icons/icon.svg', 'labels' => 'LLL:EXT: someext/Resources/Private/Language/locallang_mod.xml'
