So that the problem is babel version in react-scripts? @mike-lischke

I'm pretty sure that the problem is babel version of the react-scripts. And it doesn't support Typescript 4.x yet. I upgraded react-scripts to 3.4.3 but it didn't support too. Btw...

Our product is in development and when we release it then I will send details. By the way I like it.

Appcircle.io uses immerjs

In my case, it did not load service worker because file name was pascal-case.
