Certain table type crashes studio upon defining duplicate key

When creating a table with a specific type, defining a duplicate key crashes studio, and reentering the place sometimes crashes studio, and editing the table can result in the same crash.

Example:

local ExampleTable: {[string] : {Track : AnimationTrack, Connections : {RBXScriptConnection}}} = { -- The type
	Key = "hi" -- Works fine, no issues
	Key = -- Crashes studio
}

Reproduction steps:

1. Make a table with the following type

local ExampleTable: {[string] : {Track : AnimationTrack, Connections : {RBXScriptConnection}}} = {}

2. Define a key

local ExampleTable: {[string] : {Track : AnimationTrack, Connections : {RBXScriptConnection}}} = {
	key = "hey",
}

3. Define the same key again

local ExampleTable: {[string] : {Track : AnimationTrack, Connections : {RBXScriptConnection}}} = {
	key = "hey",
	key = "yo"
}

Expected behavior
