Welcome @임한울(Hanwool Im) !

This error means that during some operation (e.g upgrade or migration) something is wrong / not recognized / not valid in current system. 

If you deleted content from UI and something is not recognized already it might still leave some code. Would be good to check the source / storage format of the page. 

It was easy on on-prem versions of Confluence to modify source code. On Cloud it might not be possible, so maybe you can only view source and verify if anything suspicious is there? 

If not maybe you can copy this source and paste on me page to see how it view after that?
