[Compiler Bug]: A bug with i18n translation after react compiler

[YYGod0120]

What kind of issue is this?

• [ ] babel-plugin-react-compiler (build issue installing or using the Babel plugin)
• [ ] eslint-plugin-react-compiler (build issue installing or using the eslint plugin)
• [ ] react-compiler-healthcheck (build issue installing or using the healthcheck script)

1. Change the var in app/[language]/components/Typewrite.tsx to const (use var to skip the compiler and fix the bug)
2. use pnpm dev to start project
3. Click twice on the lanswitcher and find that the Banner is not translated after the second click.

15038 involves i18n and deals with errors caused by instantiating i18next when dynamically combining multiple applications. Though the descriptions vary slightly, both issues revolve around i18n and potential related problems. There might be some common patterns or issues among them.

Thank you for your advise. I don't know if it's a problem with i18n or react-compiler. After I skipped compile, the display was normal and I didn't see any errors. So I prefer it to be a compiler problem.

By the way, I moved the problem to the branch of compilerBug. I bypassed this problem on the main branch and updated it.
