Bitwarden does not start-up

Hi,
After reporting Unexpected token in json at position 0 - #4 by vachan, I decided to uninstall and re-install Bitwarden. Installed Version 1.28.3 (535) for Mac OSX obtained from GitHub. Now my problem is even worse. I typed my email / password, and hit Login, and received the exactly same error from my post above: Unexpected token in json at position 0. Before I could not delete an item. Now, I cannot access my entire Vault. Is there any log that I can share here to see if someone can help me with this issue?
