[9.1.0] Failed to connect to the simulator: Timeout

I've seen this occasionally on every SDK as far back as I remember with VSC.  just close the sim and run the app again.

Same here. I get this sometimes as well, but only temporarily. In general my (slower) notebook seems to run into it more often than my PC. Overall I feel like it has been happening less recently, but that is just a gut feeling.

Currently I see the "critical compiler error" much more often, and sometimes the infamous fatal "Kill app to launch the app" when opening the app from the glance.

Is it persistent for you?

With 9.1.0 I can run an app in the simulator once and then it stops working. With older versions I had this happen rarely and was able to fix it with a restart of VSC. Now I need to restart my PC which means it is barely useable.

I've noticed that with updates to VSC, it's become a bit of a memory hog.  Do other things like your browser slow down much when you use it?

I observed that there's something fiercely looping in the Monkey C VSCode extension. I ended up extracting the syntax highlighting portion from it so I can continue to use that without whatever else is grinding the CPU.

In Windows, I've taken to closing the Java process with Task Manager.  I don't think closing/reopening VSC is doing enough.

If I don't restart Java regularly, then I get errors when going into the Edit Storage Properties menu all the time.  And then eventually a timeout.  My Java is consuming over 1GB RAM regularly before I close it and the Sim seems to restart it reliably.
