My AWS Account got locked

Hello.

If the resource is not displayed, does that mean there is a permissions error?
Do you get any error messages when you try to display it?
Just to be sure, is it possible that the displayed region is different and the resources just seem to disappear?
If the displayed region is different, try changing it from the top right of the management console.

If you can sign in to your AWS account, I don't think your account is locked.
If you don't see your AWS resources in any region, I recommend opening a case with AWS Support under "Account and billing."
Inquiries under "Account and billing" can be made free of charge.
