I’m sorry to hear about the issues you’re experiencing. I encountered a similar situation once where instances were linked to outdated components that were no longer in use. In that case, reconnecting or swapping them with the correct components resolved the problem.
I see you’ve already reached out to our support team, which is great! They’ll investigate your case and get back to you as soon as they can. Please continue to communicate with them for further assistance.
I had the same problem with multiple components from a library.
They all used a common icon subcomponent, one of which had a variant referring back to a relegated library.
Detaching that variant fixed the problem for me.
