Internal error server on docker after server crash: oc_authtoken table possibly corrupted, can't be dropped

I’m running Nextcloud 21.0.2 inside docker. Yesterday, after my server crashed, I was welcomed with an internal server error screen at my cloud’s landing page. Nextcloud’s log shows something like this every time I refresh:

}

It seems like the table nextcloud.oc_authtoken is not found, but at least SHOW TABLES shows it in the Mariadb container.

Following this thread, I tried this without success:

MariaDB [nextcloud]> describe oc_authtoken;
ERROR 1932 (42S02): Table 'nextcloud.oc_authtoken' doesn't exist in engine
MariaDB [nextcloud]> CREATE TABLE oc_authtoken (
    -> id BIGINT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    -> uid VARCHAR(64) NOT NULL,
    -> login_name VARCHAR(64) NOT NULL,
    -> password LONGTEXT,
    -> name LONGTEXT NOT NULL,
    -> token VARCHAR(200) NOT NULL,

    -> last_activity INT(10) NOT NULL DEFAULT '0',

    -> password_invalid TINYINT(1) NOT NULL DEFAULT '0')
    -> ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
ERROR 1050 (42S01): Table 'oc_authtoken' already exists

Also, I’ve tried to drop the table first, but the process seem to hang: no feedback, and it seems to never end.

Any recommendation? I’m quite lost.
