Hi Ger, Thank you so much for your insights. The connection to INT32_MIN and the potential for an underflow or overflow error does seem plausible, especially given the remarkable error value that aligns with INT32_MIN/1000. I haven't delved into debugging at that level yet, but your suggestion provides a solid starting point for further investigation.
