Godot 4.5.1 crashes instantly when enabling Dialogic 18.0-alpha in the Project Settings (macOS ARM64) #2691
Description
The problem
Describe the bug
Installing the Dialogic 18.0-alpha plugin does not immediately crash Godot.
The crash happens only when enabling the plugin inside:
Project → Project Settings → Plugins → Dialogic → Enabled (checkbox)
The moment the checkbox is clicked, the entire Godot editor instantly closes, and macOS generates a crash report.
The crash log shows the error originates from:
EditorPluginSettings::_plugin_activity_changed()
meaning the crash occurs exactly when Godot attempts to activate the Dialogic editor plugin.
⸻
To Reproduce
1. Create a new Godot 4.5.1 project.
2. Copy Dialogic 18.0-alpha into res://addons/dialogic/.
3. Open the project (no crash yet).
4. Go to Project → Project Settings → Plugins.
5. Tick the Dialogic “Enable” checkbox.
6. Godot immediately crashes.
⸻
Expected behavior
Enabling the plugin should activate Dialogic normally without closing the editor.
