Copilot Always Crashes in Visual Studio 17.3.0 Preview 5

[nolanblew]

I can't seem to get copilot to work at all in the latest preview version of Visual Studio 17.3.0 Preview 5. I have successfully installed and logged into copilot on my computer, however I cannot use it.

Looking at the copilot output log, every time it attempts to generate a suggestion I get the following error:

[Error] An error occurred for 'OnCompletionElapsed': System.Threading.Tasks.TaskCanceledException: A task was canceled.

Note that these duplicates are most likely me triggering copilot several times. Not much more info is shown other than a task was not successful and cancelled.

Restarting Visual Studio, my PC, and uninstalling/reinstalling copilot has not fixed the issue.

Update with Visual Studio version 17.4.0 Preview 1.0 and Copilot 1.43.0.0 - Copilot works for a very short period of time (perhaps about 1-2 minutes) before crashing like this again. Only way I've been able to get it to come back is by closing and re-opening VS

I am on 17.3.3 and it crashes visual studio all the time with execution timeouts. I have restart visual studio then it works for a few minutes then crashes again.

I'm having this happen as well.
