Extension issue

- Issue Type: `Bug`
- Extension Name: `vscode-graphql`
- Extension Version: `0.3.10`
- OS Version: `Windows_NT x64 10.0.19041`
- VSCode version: `1.50.1`

```json
{
"messages": [],
"activationTimes": {
"codeLoadingTime": 19624,
"activateCallTime": 20,
"activateResolvedTime": 18,
"activationReason": {
"startup": false,
"extensionId": {
"value": "GraphQL.vscode-graphql",
"_lower": "graphql.vscode-graphql"
},
"activationEvent": "onLanguage:graphql"
}
},
"runtimeErrors": []
}
```

When I start vscode with the graphql extension, I get this error: "Extension has caused the extension host to freeze".
Also, ctrl-click to go to definition of graphql schemas doesn't work (even if they are on the same file).
