Local by Flywheel stuck at "Checking system"

For some reason the virtualbox process was spiking the cpu usage. I uninstaled virtual box.
Now Local won´t start.

I tried to reinstall virtualbox 6.0, but my system (Mac Os El Capitain) wont allow it,
I tried to reinstall Local but it still stucks at “Checking system”.

Any suggestion that can help me?
