I have attempted to replicate the issue on my end, but everything is working as expected. I am using Drupal 11 along with the same module version you mentioned: 3.1.x-dev.
And using PHP 8.3.9.

Testing steps:
- I created a field and enabled multiple sub-fields.
- I was able to successfully add a subfield after creating a text field without encountering any errors.

Please let me know if there are any specific steps or configurations I might have missed, and I’d be happy to re-test accordingly.

Thank you!

I'm also on 10.4.7 but havn't been able to reproduce the error. I think it could be triggered from this line: https://git.drupalcode.org/project/custom_field/-/blob/3.1.x/src/Plugin/.... I'll address it with a condition check in the patch I'll create for https://www.drupal.org/project/custom_field/issues/3527541 🐛 When adding a long text sub field the max length stays filled in as 255 Active and hopefully that would resolve the issue. If there's any additional steps though that could help make this error consistently reproduced, that would help me verify the fix.
