Deno LSP panicks if VSCode window has unsaved newly created TypeScript files

[kLiHz]

Version: Deno 2.1.4 (stable and canary)

How to reproduce:

• Install Deno
• Install Deno extension in Visual Studio Code (either stable or insider)
• Create a new window in Visual Studio Code
• Create a file (e.g click "New File")
• Set file source type (e.g. click "Select a language") to "TypeScript"
• Got "The Deno Language Server server crashed 5 times in the last 3 minutes. The server will not be restarted. See the output for more information."

The output:

  executable: C:\Users\Henry\.deno\bin\deno.EXE

Screenshot

I first encountered this bug a while ago, but at that time I couldn't locate its cause. Recently I just accidentally found the way to reproduce it so I'm filing this issue.

With RUST_BACKTRACE=1 it still didn't give much information, and with RUST_BACKTRACE=full:
