[4.x]: Internal Server Error when creating new fields

What happened?

Description

When creating a new field, the browser hangs and finally returns an Internal Server Error. This is not a Craft error but a (MAMP) server error. Here's the error from my Apache log:

[Fri Mar 17 11:48:43.486687 2023] [fastcgi:error] [pid 40930] [client ::1:56351] FastCGI: comm with server "/Applications/MAMP/fcgi-bin/php8.0.24.fcgi" aborted: idle timeout (30 sec), referer: http://xxx/admin/settings/fields/new?groupId=3&site=default
[Fri Mar 17 11:48:43.495330 2023] [fastcgi:error] [pid 40930] [client ::1:56351] FastCGI: incomplete headers (0 bytes) received from server "/Applications/MAMP/fcgi-bin/php8.0.24.fcgi", referer: http://xxx/admin/settings/fields/new?groupId=3&site=default

Note that for PHP 8.0.24 I have a max_execution_time set to 120

It appears the field has been created when I reload the Fields page. I'm just not sure if everything has been correctly written out to the project config.

1. Create a new field and press save

Expected behavior

Should return successful

Start by reproducing the save action at /admin/settings/fields/new?groupId=3&site=default with the reported Craft CMS, PHP, MySQL, and MAMP versions, then inspect the Apache FastCGI errors. Done means creating a field returns successfully without the 30-second timeout and the field is correctly written to project configuration.
