[macOS/arm64] Crash on loading any core downloaded via the online updater — CODESIGNING kill in dlopen

Is there an existing issue for this?

• This is a bug in RetroArch frontend
• I have searched the existing issues

Description

I’m running Retroarch v1.20.0 on an M1 MacBook Pro. I updated this core today as well as the Beetle PSX / PS1 (software) core. launching a game using this core caused RetroArch to crash immediately.

Other relevant information: I also downloaded the latest stable mGBA core today and shortly after that is when the issue started. Attempting to launch games from both these cores (but not mGBA or other cores) caused retroarch to crash. I reverted the core to a prior version and launched a game using the Gambatte core without issue. I also removed the mGBA core as a troubleshooting step, but the issue still persisted until I rolled the core back to its previous version.

Expected behavior

Game should launch without issue.

Steps to reproduce the bug

1. Download a Gambatte GB / GBC core higher than v0.5.0.
2. Launch a game that uses the above core.

Use the crash trace's libretro_get_system_info -> command_event path as the entry point, then trace how online-updated Gambatte cores are loaded through dlopen on macOS/ARM64. Reproduce with a Gambatte core newer than v0.5.0 and compare it with a prior version; done means the updated core launches without the CODESIGNING kill.
