[0.3.7, MacBook Air M1 2020] Pressing "Start Mining" while CPU/GPU mining have been toggled off in settings results in unresponsive state that requires restart

[SolfataraEmit]

Describe the bug If a user disables CPU and GPU mining and then clicks the "Start Mining" button, Universe enters a state where the "Start Mining" button is greyed out and in a perpetual loading state. At this point, the user is unable to either stop this process or enable one of the mining methods from options via the front-end, and is forced to close and restart Universe.

Universe v0.3.7

To Reproduce

1. Make sure you are not currently mining.
2. Turn off GPU and CPU mining in options
3. Attempt to start mining. Note that the Start Mining button enters an unresponsive state and the user is unable to stop this or turn on any mining settings while this state continues.

Expected behavior Either that the user is unable to start without at least one method of mining being turned on in settings, or a prompt to indicate that both methods are turned off and an option to turn them on before starting up.
