Language switcher block hides for authenticated user I have a language switcher added to my site. It works fine as long as I'm an unauthenticated user. Logging into site replaces it with:

&lt;span data-big-pipe-placeholder-id="callback=Drupal%5Cblock%5CBlockViewBuilder%3A%3AlazyBuilder&amp;amp;args%5B0%5D=languageswitcher&amp;amp;args%5B1%5D=full&amp;amp;args%5B2%5D&amp;amp;token=nsR3jJa8bJz_M5rp3ogwQZ8Ownrs-S1wckm2wsrv1BY"&gt;&lt;/span&gt;


I see this behavior also  when I add a message block to any of the regions.

I'm also using big pipe. Could it be causing some issue? Is this a bug with language switcher block?

Any help is appreciated.

Thank you
Things you can try one of the following:  


Uninstall Big Pipe module
Try switching to another theme. It might be that the active theme has a JS error which breaks the execution of the Big Pipe
Enable JS aggregation if disabled, or disable it if enabled
Check for console erros in the developer tools
