Error after update – can’t find blocks/comments.php

Can you log into the server via FTP or the admin panel? If so try uploading the comments.php file from a fresh WordPress download into the wp-includes/blocks/ directory? If the file was somehow deleted, this should restore it.

That helped, now I’m getting…

I would prefer not to, but it’s looking like that’s the next step…

@jkolko Please were you able to resolve this error? I have the same problem.
