Short description of error
Pressing autocomplete after entering bpy.context.tool_settings. into the Py Console prints a strange warning message to the system console. Just reporting it incase it wasn't supposed to be there. The message:

WARN (bpy.rna): C:\Users\blender\git\blender-v310\blender.git\source\blender\python\intern\bpy_rna.c:1352 pyrna_enum_to_py: current value '0' matches no enum in 'ToolSettings', '(null)', 'uv_relax_method'

1. Open Blender.
2. Go to the Scripting workspace.
3. Enter bpy.context.tool_settings. into the Py Console and press Tab or Console > Auto Complete.
4. Warning message prints to system console.
