Downgrade to version 3.7.55.3 and it works again.

Thanks for reporting that. I’m not able to reproduce but suspect it has something to do with CP resource caching. Should be fixed for the next release.

If you’d like to test, change your craftcms/cms requirement in composer.json to v3.x-dev as 3.7.56 and run composer update.

Craft 3.7.57 and 4.2.8 are out now with that fix.
