Run composer du once. We're aware of it: yiisoft/composer-config-plugin#21

I got the same error like this after reinstalling, and running composer du command

I have fixed this problem with change ./runtime/build/config/web.php. I moved $params = (array) require __DIR__ . '/params.php'; in the bottom of $_ENV = array_merge((array) require __DIR__ . '/envs.php', $_ENV); (idk why this can be happen). I also changed 'Yiisoft\\Yii\\Cycle\\Conveyor\\SchemaConveyorInterface' from &$params to $params.
