kotlinx.coroutines.channels.ClosedSendChannelException: Channel was closed

[emirhangulmez]

I live in a issue on when starting WorkManager.

My actions are in order:
I'm putting a second on the cryptocurrency.
I press the add button.
When I come to the main screen and wait for about 10 seconds, I get this error.
