Incorrect ts(7053) error when updating json file

Bug Report

I have strings stored in a json file.
I did set "resolveJsonModule": true, in the tsconfig.
I import the strings as follows:
import * as strings from '../languages/en.json';

Works perfectly.

When I add a string in the json file and I then try to use that new string, intellisense always gives me the ts(7053) error.

Everything builds and works but the code remains underlined as a problem.

The only workaround I found to get rid of the incorrect report is to close VSCode and reopen it.

Broken in TypeScript v4.1.5
Works in TypeScript v4.0.5

Riproduci il problema con resolveJsonModule abilitato, un file JSON importato e una stringa appena aggiunta, confrontando TypeScript 4.1.5 con 4.0.5. Inizia esaminando il comportamento del language service alla base della diagnostica ts(7053) e verifica che la diagnostica scompaia senza riavviare VS Code quando il JSON cambia.
