If you abort the trip from Settings down on the left and start a new one it should work.
Alternatively:
Open up Developer Tools in Chrome or Firefox and go into "Console" and write the following:
localStorage.clear();
And press enter. Then try again to open up Singleplayer.
Here is how to open Developer Tools and Console - https://balsamiq.com/support/faqs/browserconsole/
