The last 3 patches did not work for me on Drupal 10.1, unfortunately. I created a merge request adding simple validation before setting weights, which I belatedly realized is the same as the patch in #20.

The larger issue seems to be that locked languages (and the default language in my case) cannot be loaded as ConfigurableLanguage entities.

Since the last patches did not work for me on Drupal 10.1.x.
Thus I have created a new patch and its is working fine.

Kindly review the patch.

I've a patch from this issue on few projects, however I believe the root cause is same as @Dropa mentioned on #21 & #22. Tried to reproduce the issue with steps from #36, but no luck. So I'd vote for closing this as outdated/cannot reproduce (on clean install). The missing configuration should be rather easy to find with https://www.drupal.org/project/config_inspector → now that 📌 Add config validation for weights (blocks, filters, etc. all use weights) Fixed has landed on 10.3.x

I had this issue on Drupal 11.0.4 and it was because there was no language.entity.en config entity. There were such entities for various other languages, just not en. I have no idea how that happened.

Just because it might mask an underlying issue is no reason not to make the updateLockedLanguageWeights method more bulletproof.

I've attached my attempt to do that based on D11 dev of Oct 18, 2024.
