TYPO3 Core

Same problem in TYPO3\CMS\Extensionmanager\Utility\UpdateScriptUtility::determineUpdateClassName. Now I can't even use the extension manager :-(

I have a normal 9.2 installation in composer mode. I cannot install any language packs in the backend. Updating will show all language packs as being "not available."

The problem seems to be here:

$absolutePathToZipFile is within the var path, but writeFileToTypo3tempDir requires the path to be inside PATH_site."typo3temp/". For composer installations or when TYPO3_PATH_APP is set manually, var is not inside typo3temp any more since 9.2, so writeFileToTypo3tempDir cannot be used here.

Same problem here, also in a composer installation.
