Start by tracing craftcms/cms/src/services/ProjectConfig.php around lines 1645–1652 and the related clearDirectory calls in craftcms/cms/src/helpers/FileHelper.php. Reproduce the project-config write during the category operation and determine why removing the configs directory fails; done means the operation completes and project config files are written successfully.
