Steps

As mentioned later, it's a good idea to "Run Steam as administrator" first.

Right-click Steam in your library and select "Properties"

From "Installed Files", select "Verify integrity of game files"

It will say "Verifying integrity of game files".

And when it completes successfully, it will say "2 files could not be verified and will be reacquired.",

and there will be some trace of a download in your download history.

Then, when I launched GTA5, the main menu appeared without any issues!

It was probably the first time I'd launched it in 100 years, and it started right in the middle of the game.

Correspondence with Support

I'll also include my correspondence with Rockstar Support, just in case.

I inquired about this issue, attaching the CD code and purchase details, and here was their response.

They responded very politely in Japanese.
