Hello,

Thank you for reporting this issue. I can confirm that this is indeed the issue. It looks like I named some files with the upper case for the first character, but did not fix all yaml in libraries.yml. I think the best way forward will be to make sure it is lower case for both. I will get this pushed up soon.

I pushed up an update. Please, check to make sure this fixes your issue.

Thank you again!

This fix has been confirmed in a duplicated issue:
https://www.drupal.org/project/inline_formatter_field/issues/3414856#com... 🐛 Inline formatter field not show ace editor Active
Marking this issue as fixed.

Closing this as it is part of the 4.0.0-rc3 release.
