Difficult to say something, as I can't reproduce the error. Using Chrome with user logged in into the google account, no incognito, and it works just fine.
Are you using any proxys?

Provide your LS version and where it is installed (own server, uni/employer, SaaS hosting, etc.).
Always provide a LSS file (not LSQ or LSG).
Note: I answer at this forum in my spare time, I'm not a LimeSurvey GmbH employee.
We have web application firewall, a kind of proxy. We have already tested disabling this feature, without success. With the json message stuck on the screen there is a JavaScript error. I don't know if it is related.
