How can I get VS Code LaTeX Workshop to choose the correct Latex distribution?

I have installed two Latex distributions on my PC, i.e., Ctex and Texlive 2020. VS Code LaTeX Workshop keeps using Ctex to compile latex files. How do I force VS Code to compile with Texlive 2020?

For some reason, I need to keep the Ctex on this PC. My settings.json of VS Code LaTeX Workshop is as follows. In particular, I have specified the path of Texlive 2020. However, it still cannot compile with Texlive 2020.
