React App is not reloading in devcontainer on windows 11

I followed the instructions of this tutorial (https://youtu.be/KFyRLxiRKAc) and rewatched it several times but somehow it won't work for me. After I reopen the folder in the devcontainer and run npm start, the app is loading for several minutes until the browser opens localhost:3000 and presents the app. Now if I'm editing Code of the app, like changing the text of the create-react-app it won't reload at all. To detect changes I would have to restart the container but even that would take several minutes.

How can I solve the issue?

EDIT: I already tried setting CHOKIDAR_USEPOLLING=true and FAST_REFRESH=false but neither of them makes a difference

.devcontainer/.env

FAST_REFRESH=false
CHOKIDAR_USEPOLLING=true
