DANG Simulator fails to start TRY AGAIN

[MarioDings]

Tried everything. 

All the simulator says is "DANG Simulator fails to start "

And Studio says: 

App msg queue full, see https://dev.fitbit.com/kb/message-queue-full for recommendations.

Only Versa is affected. the others (Ionic, Versa Lite, Versa)  run (almost) perfectly.

Even re-installing the simulator had no effect (Windows10)

Your clock or app is doing too much, blocking the event loop for too long. This causes the app/simulator to crash as you can see. You'll need to debug your code to see where you're blocking for too long, and chunk that work down using setTimeout.

[MarioDings]

Perhaps, but I can't get it to uninstall.
So how do I uninstall from the simulator if the "uninstall" doesn't work.

[MarioDings]

Still no solution. Please clean my simulator on your server.

Finally found the answer elsewhere in the community. There was a (hidden) map in the directory which I deleted. Problem solved.

What is the path to this (hidden) map? I am on Windows 10.

[MarioDings]

C:\Users\%user%\AppData\Roaming\Fitbit OS Simulator

Thank you. This does not work for me, although it does for others. I have a laptop (Windows 10) and the simulator works there. The simulator does not work on my Windows 10 desktop (will try on others). Tired reinstalling, rebooting, etc. I can't get much from the log except a bunch of retries and fails. Just for information, here are the final entries showing that something is not responding:

[2020-02-05 18:17:30.904] [error] Simulator hosts failed to start: MethodCallTimeout: No response received for RPC call to 'initialize'

Let me elaborate a bit more:

I deleted the whole directory C:\Users\%user%\AppData\Roaming\Fitbit OS Simulator.

In my case c:\gebruikers\mario\AppData\Roaming\Fitbit OS Simulator.  🙂

I did not reinstall,or delete the application itself.

I also found out that I get a lot of errors when the laptop is very slow, or when the internet connection is bad.

Let me ask you: does the simulator not start up at all? Not even with the logo shining?

does nothing work on the simulator, on any type of device? Can you switch to another device, like Versa 2?

[adbokat]

Thank you. Yes, I delete that entire directory prior to starting. It tries
to start, saying "Here we go" and "Simulator loading," eventually going the
"Dang" and Simulator failed to start messages.

I did not want to mess up my actual Versa 2, so I concentrated on the
simulator. I have no apparent problem with the development studio or the
Fitbit app -- just the simulator.

Comparing logs for the laptop where it works and the desktop where it
fails, I see the problem starting with an RPC call:

[2020-02-05 17:50:14.785] [info] appsim exit code: 1 (signal null)
[2020-02-05 17:50:14.909] [warn] 6 retries left: MethodCallTimeout: No
response received for RPC call to 'initialize'
[2020-02-05 17:50:19.914] [info] shell->app:
{"id":0,"method":"initialize","params":{"capabilities":{"protocol":{"maxMessageSize":536870912}}},"jsonrpc":"2.0"}

Hoping someone from Fitbit can tell me why the RPC is failing.

Stuck with the same problem.
