Version 4.50.4 to 4.60.1 error with can't load richeditor at product editing page

If you install a clean 4.60, not an upgrade from 4.50, will there be the same error?

Install chean 4.6 is no this error

I find a similar topic:https://www.nopcommerce.com/en/boards/topic/81891/missing-richeditor-html-editor，It could be an issue with the multi-language pack. I changed to English and the site works fine, but I still can't load the richeditor。

Today I tried to install a new nop4.62 website, using the new database, the result can load the text editor, when I modify the Appsettings.json, change the link of the database to the original database, the text editor cannot be loaded, it seems that there is still a problem with the database data. Is there a way to import the data from the old database back into a new database? Importing data using SQL Server Management Studio is not always fully imported.

I feel that it is a problem with the language pack, after I overwrote the original database with the previous version 4.50, the text editor can be loaded normally, but there are many words that are not translated. I was trying to export the 4.60 language pack and then import it, and I got this error.

The MERGE statement attempted to UPDATE or DELETE the same row more than once. This happens when a target row matches more than one source row. A MERGE statement cannot UPDATE/DELETE the same row of the target table multiple times. Refine the ON clause to ensure a target row matches at most one source row, or use the GROUP BY clause to group the source rows.
