Stale exported resources could contribute to such a problem, but they would
not really the root cause, and they might not be a cause at all.

The error message says that the problem is two distinct declarations of a
resource "Swift::Ringsync[account]". The most likely cause is that you are
both collecting that resource and declaring it locally for the same node.
For example you may be doing something like this:
swift::ringsync { 'account':
# properties
}
Swift::Ringsync <<| |>>
where some node has exported a Swift::Ringsync['account'].
Purging exported resources would normally be an effective -- albeit not
necessarily correct -- solution to such a problem, at least for one run.
If purging doesn't solve the problem even temporarily then it's likely that
the node in question is the one exporting the resource, too. In that case
the correct solution would be for the node to rely on collecting the
resource it itself exported instead of redeclaring it as a local resource:
# This exported resource assumed already present
@@swift::ringsync { 'account':
# properties
}
# Removed the local redeclaration of Swift::Ringsync['account']
# Still want to collect all these,
# including those declared by this node:
Swift::Ringsync <<| |>>
