Fitbit Studio Simulator error

[SunsetRunner]

Utilizing the simulator has worked perfect up till today. Deleted Sim and reinstalled no luck. Mac OS operating system and computer.

1) Fitbit Studio build Project

2) Open Simulator

3) Select Versa Simulator

4) Run

App loads and runs fine, then...

1) Make a change in app using fitbit studio

2) Build or just go strait to run

3) The below error occurs and can not find a solution 

(unable to paste screen shot for some reason)

---------------------

Dang

Simulator failed to start: read ECONNRESET

Try Again

-------------------

Try agin just sits there and spins and never does anything else. Only option is to exit simulator and start it up again to run changed app. As I previously stated nothing has changed, no updates nothing, worked up till today just fine.

Thanks...........

Bump......

I cant be the only one having this issue?????????

[SunsetRunner]

So it has gone from bad to worse. Now Simulator opens and immediately closes. Uninstalled and reinstalled no help I also see in Dashboard under Manage Account Access that Fitbit Simulator has disappear. Can it get any worse?????

[SunsetRunner]

Doing nothing different, not even shutting the computer off, nothing, I can get to the login screen and back to the original problem. Only once can you run an app or clock face, then have to close simulator and reopen to run again.

Is it just your project which causes this issue, or does the same happen with the default digital clock project?

Can you also collect logs and send them to me via a private message?

Logs:
OS X: ~/Library/Logs/Fitbit OS Simulator/log.log
Windows: %USERPROFILE%\AppData\Roaming\Fitbit OS Simulator\log.log

If the bug is reproducible, it's best to delete the log file then restart the simulator & repro the bug, to reduce the amount of noise in the log file.

If the bug relates to a particular app, send the Studio project export.

Thanks

Today I was able to narrow the problem down to the Heart Rate Monitor Code I am using. I have written a total of 10 clock faces / apps using the same code and worked fine up until the other day. I am going to play around with it and see if I can figure out why it no longer works and what I need to change in the current code. If not I will PM you as requested with logs etc....

[SunsetRunner]

Able to fix my code (still not sure why it use to work) to display the heart rate. 

To reiterate: Error in Heart Rate code will cause Fitbit Simulator to crash on second time running it. No error during build or Build Output. On first load you just don't have any info displayed in simulator for Heart Rate. Removing the line: hrm.start(); simulator does not crash. I wish I could tell you the exact problem with my code but I just started over from scratch.

Same problem. No solutions that I saw in various places work. Here is my log:
