Sudden Error/Bug: "Handle contains Attributes", but RBX_AutoSetupped can't be removed, can't post to marketplace while using avatar setup

The upload dialog fails with:

‘Handle’ (or its descendants) contain Attributes. You need to remove Attributes from the following: Jeans.Handle

At the same time, the Output window shows this error from Studio’s Command Bar:

Attempt to assign attribute RBX_AutoSetupped. CoreScript permission required - Edit
Script 'CommandBar', Line 6

There is no way out, I cannot upload anymore and this error has only come up suddenly. Urgently need support. Thanks!
