Launching Virtual Lab hangs with solution

Just in case someone else runs across this. While on Chrome and attempting to launch the virtual lab it seemed to hang indefinitely. (In my case I had previously run another lab)

I was able to get it working by deleting a few cookies including the one for Dremio University and Cloudflare.

Right click lock in browser location bar and select cookies

Highlight cookie and click remove.

A simple page refresh seemed to work from this point for me.
