Error (The specified module could not be found / plugin cannot be loaded for module "QtQuick")

First, I'm Japanese, not fluent at English sorry.
I started to learn Qt and currently stucking in this error.
~~The important error content is garbled.~~
I changed my Windows settings from Japanese to English, and the garbled characters were cured. Apparently, Qt does not support multiple languages(?).
(I spent so long time,5~8h, to download Qt, don't wanna redownload tbh)
