yoku0825です。
2通目のお返事が見やすくてありがたいです。

ALTER TABLE .. ROW_FORMAT = COMPACT が成功しないテーブルのエラー、
"Invalid default value for 'comment_date'" でググってみたらこんなのが出てきました。

https://7me.nobiki.com/2020/01/31/mysql-timestamp-invalid-default-value-0000-00-00/


SET GLOBAL explicit_defaults_for_timestamp = ON;
-- 一度mysqlコマンドラインクライアントを終了して再接続

ALTER TABLE .. ROW_FORMAT = COMPACT;
ALTER TABLE .. DISCARD TABLESPACE;
-- copy ibd files via shell
ALTER TABLE .. IMPORT TABLESPACE;

ではどうでしょうか？
