xampp QStandardPaths: el directorio de tiempo de ejecución '/run/user/1000' no es propiedad del UID 0

Tengo un problema al ejecutar xampp y abrir la carpeta de la aplicación, ya que me sale el siguiente error:

QStandardPaths: runtime directory '/run/user/1000' is not owned by UID 0, but a directory permissions 0700 owned by UID 1000 GID 1000
QStandardPaths: runtime directory '/run/user/1000' is not owned by UID 0, but a directory permissions 0700 owned by UID 1000 GID 1000

"Session bus not found\nTo circumvent this problem try the following command (with Linux and bash)\nexport $(dbus-launch)"

Tengo Dolphin instalado en el sistema, pero Thunar es el administrador de archivos predeterminado.

Sin embargo, xampp también toma a Dolphin como administrador de archivos principal.

# sudo ./manager-linux-x64.run
Executing Dolphin with sudo is not possible due to unfixable security vulnerabilities.
