Hi,
sounds like your name mapping repository might be out of sync with the actual DOM properties , pretty common issue when TestComplete caches older object definitions.
I have dealt with this exact problem before, usually involves refreshing the object spy mappings and adjusting the identification properties to use more stable attributes like data-testid or xpath instead of dynamic IDs.
Could probably get your scripts running again in a couple hours by updating the recognition criteria and adding some wait conditions for those flaky elements.
You can reach out to me on my email here
