2017.3 trouble with code completion

I along with multiple colleagues have been seeing issues after upgrading to 2017.3. We are seeing issues while trying to get code completion to popup. It seems to work for a little bit after upgrading but after trying this morning I'm seeing the same thing as what others have been describing. 

The issue is when trying to bring up the code completion flyout by hitting control + space results in nothing happening. I have looked in the logs and am seeing a ton of exceptions being thrown. They all appear to be the same:

Ive tried removing workspace.xml, the preferences directory with no luck. It seems to only be an issue on my Mac and do not seem to have this issue on my Linux desktop. Ive also heard someone has the same problem with a hello world app as well so its not just our project.

Any thoughts?
