Bad Gateway 502 - if breakpoints are aktivated in code

[moinomedia]

I am working on macOS and have installed PHP version 8.1 via Homebrew. I installed Xdebug afterwards using PECL. I am using PHPStorm.

Xdebug appears to be correctly activated. As soon as I set a breakpoint in the IDE, I receive a 502 Bad Gateway. If I deactivate the breakpoint, the web project can be accessed normal without errors.

nginx-error.log
*1 upstream prematurely closed connection while reading response header from upstream

fpm-logs
[pool valet] child 68149 exited on signal 11 (SIGSEGV) after 6.979023 seconds from start

Is this a known configuration issue? I have been trying to find the cause for several days and would greatly appreciate exchanging possible solutions.
