Red-discordbot: [Core] Crash | Red 3.3.1

Other bugs

What were you trying to do?

Use shutdown or restart (using batch file for Windows).
When using restart and the batch file it just repeats for 4-5 seconds until it finally starts the bot again.

What were you expecting to happen?

For the bot to exit/restart properly.

What actually happened?

    raise RuntimeError('Event loop is closed')
RuntimeError: Event loop is closed

After this it starts to repeat until starting the bot again, or just ends, after the repeats, if using shutdown.

How can we reproduce this issue?

Not a clue.

This is the first I've seen this issue come up since we started manually handling closing the event loop (see BPO above for why) and wait 2 seconds for outstanding transports to be closed. That may not sound like much time, but considering that waiting happens after canceling out everything else the bot is doing, we expected it to be enough. We can't go much higher than this without running into issues with process managers killing services that don't close when told to do so.

I'm sorry. Don't really understand all of that stuff and what you said.
Just wanted to share what was happening.
