Dead backend after uninstallation of Jollyany package

[ReLater]

• Joomla 3.10.3

• I installed astroid-package-v2.5.11.Jollyany-Template.zip

• In administrator/index.php?option=com_installer&view=manage I checked the Jollyany package and clicked "Uninstall".

• Afterwards the whole Joomla backend is dead and displays
  500 Library path /libraries/astroid/framework/library/astroid cannot be found. /libraries/loader.php:438

• Thrown by
  JLoader::registerNamespace() | JROOT/plugins/system/jollyany/jollyany.php:10

EDIT: And the jollyany package is still present in database #__extensions

Rename the following folders via FTP.
/libraries/astroid to libraries/astroid_old
/plugins/system/astroid to plugins/system/astroid_old
Backend will be available then and reinstall the framework and you should be good to go.
