I have a problem about bibliography when build `.tex`

In the Visual Studio Code with LaTeX-Workshop, the built pdf cannot contain the bibliography. However, in the TeXworks, the .tex file can be successfully compiled. In the Visual Code, the compiler log only show two errors but not indicate what exactly the errors are.

There is the log of compiler.

This is BibTeX, Version 0.99d (TeX Live 2019/W32TeX)
The top-level auxiliary file: main.aux
The style file: ieeetr.bst
Database file #1: refs.bib
I was expecting an "="---line 967 of file refs.bib
 :   
 :   author={G. {Zhao} and K. {Xu} and L. {Xu} and B. {Wu}}, 
(Error may have been on previous line)
