Hello,
Thank you for posting!
Per checking your account, we could see you only have a browser extension used. We recommend clearing the cache and cookies of the browser and accessing LastPass using a different browser or incognito/private window, try to launch from the web, if this works, remove and reinstall the extension in the regular browser one more time.
If your issue is not resolved, please, create a ticket for our support team.
Thank you,
Karol | Customer Care
