Is there any solution to this issue?

Please try collecting the TS Server log:

1. Set "typescript.tsserver.log": "verbose",
2. Restart VS Code and reproduce the problem
3. In VS Code, run the TypeScript: Open TS Server log command
4. This should open a large log file called tsserver.log

If you can share that file, it should contain perf information that can help us investigate the issue

⚠️Warning: The TypeScript log may include information from your workspace, including file paths and source code. If you have any concerns about posting this publicly on Github, just let me know and we can arrange something else. On our side, we only use these logs to investigate issues like this

[p32929]

I will share the logs tomorrow
