Hi @elrosi 😃 , did you happen to get to the root cause of this issue? if so, what was the resolution?

I have found a workaround by commenting out $blocks in the cache file that renders that twig, e.g.
var/cache/dev/twig/19/19b9b37ef72d8545e1d5a5eb408e85d7.php

yield from $this->unwrap()->yieldBlock('image', $context, []);//$blocks);
yield from $this->unwrap()->yieldBlock('navButtons', $context, []);//$blocks);
yield from $this->unwrap()->yieldBlock('title', $context, []);//$blocks);
yield from $this->unwrap()->yieldBlock('meta', $context, []);//$blocks);

But I am in need of a permanent solution, as that temp is wiped every time cache is cleared.
