[Bug] Server Panic/Crash when typing in CSS file (Nil Pointer Dereference)

[danielrsanches]

Description:
The Gemini Code Assist (GCA) extension is experiencing a fatal failure (panic) that crashes the Language Server Protocol (LSP) server and causes the user to be signed out/disconnected repeatedly, only when typing code in CSS files within the workspace.

The Chat and Agent Mode functionalities remain fully functional, but the Autocomplete (Inline Completion) feature in CSS triggers the server crash.

The user's workspace resides on a Google Drive directory (e.g., G:\Meu Drive...), and the GCA server shows widespread failure when indexing the files (Error: tokenizeFunc: context canceled). The fatal crash occurs during code analysis.

Repro step:
Open VS Code with the project folder located on Google Drive (e.g., G:\Meu Drive\Programação\projetos PHP\ARGUS).

Ensure the Gemini Code Assist is authenticated (Confirmed AI Pro subscription is recognized).

Open the file dsPesquisa.css (or any complex CSS file).

Type a character in the file (triggering autocomplete).

Result: The GCA server immediately crashes (Server crashed 5 times in the last 3 minutes) and the client disconnects (Error: Cannot call write after a stream was destroyed).
