Hi Dante,

Thank you for contacting us on this.

May I please ask you to create a new project and check if the issue would be reproduced for this newly created project?

If this would happen again, please send us a bug report directly from the IDE - you can find this functionality in the menu Help -> Report a Bug, please put your email and enable the 'Attach Log File' checkbox.

Also, can you please let me know if your newly created Lightning component contained any members or was there only a component file inside the bundle?

In addition, please let me know if you can open other existing Lightning components which you pulled from your org.

Thank you,

Kate
