Hi team,

Even with the current latest version (3.17.0-251008 from October 2025), dragging any asset from the BlenderKit panel into the 3D viewport crashes with the following traceback:

TypeError: bpy.ops.call() argument 3 must be str, not bool
Location:
File ".../5.1/extensions/system/blenderkit/asset_drag_op.py", line 786, in handle_view3d_drop
File ".../5.1/extensions/system/blenderkit/asset_drag_op.py", line 1208, in mouse_release
File ".../5.1/extensions/system/blenderkit/asset_drag_op.py", line 1699, in modal

The offending call (line ≈786) currently passes a boolean as the third positional argument instead of the required execution_context string ('EXEC_DEFAULT') that Blender 5.x now strictly enforces.

System details:

• Blender version: 5.1.0 (official build)
• Operating system: macOS 15.6.1 (24G90) – Apple Silicon
• BlenderKit version: 3.17.0-251008 (clean reinstall, no older versions present)

Any help would be greatly appreciated.

Thank you,
Arthur
