Core: Access Permission Error randomly occurring during runs

[IronLucario2012]

The SC2 instance will, at seemingly random, crash with an Access Permission Error for no apparent reason. Even when I've only got one instance running and it cannot realistically be my computer being unable to handle running it.

Here's the output from the terminal starting from the first sign of an error:

WARNING:absl:SC2 isn't running, so bailing early on the websocket connection.

Are there any ways I can tell why this is happening in order to fix it?
