Xdebug does not work on M1 Mac

[noahott]

I cannot get Xdebug to work on an M1 Mac. The same configuration works without any issues on an Intel Mac running the same version of macOS, 12.0.1.

This can be reproduced by starting a new environment with the default wordpress or drupal9 recipes and adding xdebug: true to .lando.yml. I have confirmed that xdebug is active, but my debugger cannot connect. If I specify a custom php.ini file that enables xdebug logging, i see:

I've also tried reverting to xdebug 2 and the same issues occur.

Getting a similar issue on WSL, tried multiple different ports.

Same thing here. Linux Mint 21.1. Could not connect to debugging client. Tried: 192.168.88.105:9003.

Creating a new MacOS user account, then reinstalling Docker and Lando solved this issue and allowed me to use Xdebug.
