🕗 Version & Regression Information
- This is a crash in tsserver.js
- This happens in 4.2.2, 4.2.3 and next (4.3.0-dev.20210305), but not version 4.1.5
- node version v14.15.4

💻 Steps to reproduce
This happens consistently for me in the OmniSharp/omnisharp-vscode repository, when opening a typescript file with 4.2 installed.
- git clone https://github.com/OmniSharp/omnisharp-vscode.git
- cd omnisharp-vscode
- npm install
- npm install -g typescript@4.2.2
- code .
- Configure vscode to use the global ts server (for me this is
"typescript.tsdk": "C:\\Users\\phil\\AppData\\Roaming\\npm\\node_modules\\typescript\\lib",) - Restart code
- Open the TypeScript output to view errors
🙁 Actual behavior
The TypeScript language server crashes. Attached is a sample log:
