Hmm, to give a status update on this, I actually have no idea how to solve this problem specifically.

There's a method in the runtime that "somehow" (?) isn't accessible after the intended chunks are loaded, so injecting a new one doesn't work.

I tried a few options already and haven't found a workaround for this yet. So it technically failing with Unknown Webpack structure is correct here 😄

Your issue states other websites also have this, could you list some more examples?

Hi! The sites I mentioned have authorization, and there is no English localization. I have something better, I did a little digging and found out that applications built with create-react-app version 3.x and 4.x look the same, the same structure, and the same error.
I did eject on version 3.4.1 and deployed the redux toolkit counter app to the cloudflare page
link to repo
Maybe this will help...
