CatastrophicError: We still have not reached idleness despite waiting for 60 seconds

**Version**
CodeQL extension version: 1.6.12
CodeQL CLI version: 2.10.4
Platform: win32 x64

Additional VS Code settings:
```
"codeQL.canary": true,
"codeQL.runningQueries.debug": true,
"codeQL.runningQueries.numberOfThreads": 4,
"codeQL.runningTests.numberOfThreads": 4,
```

**Description of the issue**

After running and then cancelling a query multiple times with the VS Code extension and also occasionally deleting the `.cache` directory in between, the following error occurred:
```
com.semmle.util.exception.CatastrophicError: We still have not reached idleness despite waiting for 60 seconds.
The scheduler knows 208 tasks, 0 poked, 1 currently running, and 0 ready to run.
```

Trying to run the query afterwards again after waiting some time succeeded without issues, so feel free to close this issue. I mainly reported it due to the following line in the log output:
```
If you see this error in a production run with the latest CLI, please file a report including the above graph dump.
```
Though maybe my system was just overloaded at that moment for some reason.
