Make sure you have Scrivener 3.1.5, which has a number of Catalina-compatibility fixes.

Yes.
I’m using version 3.15(12258).

Hmm. All projects, or just this one? – Katherine

This is in fact a known issue with 3.1.5 in Japanese. Using the older version should fix it (or alternatively using the interface in another language). It’ll be fixed in the next update.

Thanks for reply.
I found some workaround here.(Japanese)
