Update system_post_update_add_langcode_to_all_translatable_config fails

I'm having the same issue going from 10.2.2 to 10.3.2. I've tried various versions of drupal core and the issue only begins and persists from 10.3.0 onward. Attaching verbose drush output. I've attempted to clean up the output so that it is readable.

This seems to be causing a memory leak as the process will only sigterm after all available RAM has been used up.

I was finally able to resolve this issue on my Drupal 10 site. The issue was found to be a specific config file that already contained the "langcode: en" option in the configuration. This config file was part of an unused theme on my site that was never removed after it was replaced by a newer iteration of the theme. So the solution in my case was to uninstall/remove the unused theme from my site. Hopefully, this helps someone else facing the same issue.

First, I should have created the issue as a "Support request" and not a "Bug report" ... my bad.

I've also resolved the issue and it's also theme related ...

My main theme is a subtheme of bootstrap_barrio and there appears to be a problem with my subtheme's yml ... couldn't figure out what the error was so here's what I did:

- export my config with drush
- site maintenance on
- set the default theme to bartik
- uninstall my subtheme and bootstrap_barrio
- update the files
- updatedb (which ran with no problems)
- reset the default theme to my subtheme
- import my config with drush
- flush cache
- site maintenance off

Not ideal but at least I could run the updates.

I'm closing the issue.
