Intellisense hangs on "Loading..." after working correctly only once

[myounger]

Issue Type: Performance Issue

I've tried everything to get this to work correctly from running with no extensions to completely uninstalling VS Code and reinstalled following steps I found to clear all the extensions and all of the settings.

The actual issue:
When I begin typing a cmdlet or function name from a custom module, the first occurrence is fine and will auto-complete the parameters. Sometimes the second occurence will work as well but by the third time, every time, I type out a function from that module the intellisense stops responding and is stuck on "Loading..." for 30-60 seconds. It will eventually clear but this is killing my productivity. It will typically work right away if I kill the Terminal session as well but starting new terminal sessions every few minutes isn't ideal either.

Some more information. This is broken on my primary development machine. However, I do have another machine that is not having this issue. Here is what I found.

I turned on diagnostic mode for the editor services log. There is a distinct difference between the broken machine and the one that works.

Broken:

[Info  - 12:38:41 PM] OmniSharp.Extensions.LanguageServer.Shared.LspRequestRouter: Finished: Routing Request (140) textDocument/completion in 21041ms | Id='140' Method='textDocument/completion' ElapsedMilliseconds='21041'
[Info  - 12:38:41 PM] OmniSharp.Extensions.JsonRpc.InputHandler: Request 140 was cancelled | Id='140'

Works:

[Info  - 12:40:11 PM] OmniSharp.Extensions.LanguageServer.Shared.LspRequestRouter: Finished: Routing Request (87) textDocument/documentSymbol in 0ms | Id='87' Method='textDocument/documentSymbol' ElapsedMilliseconds='0'
[Info  - 12:40:11 PM] OmniSharp.Extensions.JsonRpc.InputHandler: Finished: Processing request textDocument/documentSymbol 87 in 0ms | Method='textDocument/documentSymbol' ResponseId='87' ElapsedMilliseconds='0'

You can see on the machine that breaks, it is running for 21 seconds before it "completes" and then says the request was cancelled. For the machine that works, this is a 0ms call and it returns fine.
