Button php array error

There are no steps to reproduce so I did my best by upgrading a 10.4.7 site to 10.5.0. I can't reproduce it. There is a lot of automated test coverage on plain Drupal installs ensuring that login works. So we need verified steps to reproduce this bug to proceed.

I just upgraded my dev site from 10.4.7 to 10.5.0 and I am getting the same error.

We ran into this too. Cache clear fixed it for us.
Our guess is that we're missing some step in our deploy process but we are using the drush:deploy command.

As @ramil g noted, clearing the cache appears to fix the error.

A drush cache:rebuild will do it from a command line, since the submit buttons are flaky until this is fixed.

I met the same problem after upgrading to 10.5.0.

The problem resolved via execute update.php to update the database.

updatedb clears the cache: https://www.drush.org/13.x/commands/updatedb/
I actually ran updb to resolve this as well.

I just clean the cache and the problem was solve
