Bug: Formatter causing some lines get erased

I love to use VSC Java plugin but I had so much pain working with java now.
The reason I like vscode now only for the ui but this plugin is very customisable like a way to line up curly bracket.
Now the "Format Document" is glitchy, it somehow erased some part of the code when I indent it.
I'm not sure if it's related to any tokens because when this happens, if I didn't remember wrongly, it caused the semantic highlight changed too. But then the semantic tokens bug were patched but this issue persist (still there).

Environment
Operating System: Windows 10
JDK version: 14
Visual Studio Code version: 1.60.0 before update also the same
Java extension version: -
Steps To Reproduce
Just edit the code and with comments, on performing indentation, it will cause glitches
This happens when I start typing code for long time.

I don't know if this info help, since this plugin doesn't have built-in option to line up braces plus the default switch-case indentation is weird, so I use this profile:
configuration.zip

Could it be this profile is causing conflict? I'd be glad to provide more information if needed.

Bắt đầu bằng cách tái hiện Format Document trên Windows 10 với JDK 14, các chú thích Java và configuration.zip được cung cấp, đặc biệt là sau khi nhập liệu trong thời gian dài. So sánh kết quả với tô sáng ngữ nghĩa và kiểm tra xem các dòng mã nguồn có bị xóa hay không; được coi là hoàn tất khi việc định dạng bảo toàn toàn bộ mã và giữ nguyên phần tô sáng.
