ElectrumX server terminated abnormally，help！

[nothing122232]

Can someone help me? My running result shows this situation. I am not a computer programming expert, and I built nodes based on someone else's tutorial. As a result, this prompt appeared at the end of the run. How can I solve it? Thank you
