Had a similar dilemma. The only versión that worked for me is two.2353.sixty four which I was in the position to recover working with Time Machine.

I am using WhatsApp Net alternatively and utilizing the feature "Download App" https://whatsapp35689.win-blog.com/16369744/getting-my-whatsapp-web-to-work
