TYPO3 Core

Patch set 1 for branch 9.5 of project Packages/TYPO3.CMS has been pushed to the review server.
It is available at https://review.typo3.org/59518

I get the error when a syntax error occurs in typo3conf/PackageStates.php

After adding couple of lines i could see that packageManager is EMPTY for key 'core'

Debug:
/usr/share/typo3/typo3_src-9.5.3/typo3/sysext/core/Classes/Utility/ExtensionManagementUtility.php
added three lines at beginning of public static function extPath($key, $script = '')

if (empty(static::$packageManager)) {
            throw new \BadFunctionCallException('TYPO3 Fatal Error: packageManager is EMPTY for key '.$key, 1234567890);
        }
