I didn’t manage to reproduce it, on my side I can click hundred of times and it will work each time 
Could you please open the dev tool (right click → inspect → console tab and network tab
And try to reproduce again the error on your side, once it happen you should see some messages in the console tab and the request state in the the network tab (looking like my screenshot)
If you can share how these two tabs looks when the issue happen it could help us resolve it, thanks
