IE 11 Application Hang. Reason Unknown

Question

IE 11 hangs and stops responding on one of our pages. The page relies heavily on JavaScript and crashes during one particular action the user takes. While running the IE 11 debugger, everything seems to work correctly. It makes it through all the javascript,
but the page doesn't respond.
Also, setting the Document Mode to IE 8-10 or checking Compatability Mode does not solve the issue. IE 11 still crashes. The real versions of IE 8-10 do not crash.
Here is a detailed view of the Application Error:

The javascript that runs when the crash occurs (with no errors) is as follows:
function renderObjectiveStrategies(objId,goalId){
try{
if(myRowIndex != null){
var tO = document.getElementById("tblObjectives"+goalId); //Get the table that the current objective is in
var plusRows = 1;
if(doSC){
plusRows = 2;
var r = tO.tBodies[0].insertRow(new Number(myRowIndex)+plusRows); //Insert a row below the current Objective in the tBody
r.setAttribute("id","objStgsRow"+objId);
var c = r.insertCell(0);
c.colSpan = "2";
c.innerHTML = "&nbsp;";
c = r.insertCell(1);
c.colSpan = "3";
c.className = "cellLeftBorderObj cellBottomBorderObj cellRightBorderObj";
var tS = generateNewTable("tblStrategies"+objId);
createStrategyHeaderRow(tS,goalId,objId);
createStrategyFooterRow(tS,objId);
var lstStgCt = Object.size(myObjStgs);
if(lstStgCt > 0){
for(var i = 0; i<lstStgCt; i++){
createStrategyRow(tS,"ro",tS.rows.length,myObjStgs[i]);
if(doShowNewStrategy){
var stg = getNewStrategyObject(objId);
createStrategyRow(tS,"edit",tS.rows.length-1,stg);
var myOId = new Number(objId);
var exStr = "document.getElementById('txtStgDesc"+myOId+"0').focus();";
//cl(exStr);
setTimeout(exStr,0);
doShowNewStrategy = false;
c.appendChild(tS);
}catch(e){
console.log(e.message);
Any ideas are greatly appreciated!
Thanks,
Matt

Hi Matt,
Event ID 1002 is an generic error event which occurs when application stops responding.
Based on your description, I would like to suggest you try the following to check the issue:
1. Disabling Enhanced Protected Mode
2. Delete your browser history
a. Start Internet Explorer from the desktop.
b. Press Alt to show the menu bar.
c. On the Tools menu, tap or click Internet options.
d. Under Browsing history, click Delete.
e. Select all the applicable check boxes, and then tap or click Delete.
f. Tap or click Exit, and then restart Internet Explorer.
3. Run IE with no add-ons. Click Start -> All Programs -> Accessories -> System Tools -> Internet Explorer (with no add-ons). 
4. Reset Internet Explorer settings

Please understand that reset Internet Explorer to its default configuration. This step will also disable any add-ons, plug-ins, or toolbars that are installed.
5. Remove any 3rd party anti-virus from your system.
6. Manually check for and install updated drivers in optional updates.
If the issue still occurs, you may consider to perform a system restore on your computer to fix it.
