The data output from the compiler cannot be displayed normally in the chrome developer tool

I.m a new developer,when I output data to the console in the code editor, the output result was normal before. Now suddenly there is a lot of hot-update data in the console. It cannot become normal unless I click refresh in the upper left corner.normal abnormal

I’ve been searching for a long time but haven’t found the corresponding problem. I hope the output results can become normal.
