RTVS fail to compile pdf files

R markdown fails to compile pdf files. I have tested this error with various rmarkdown files. The typical error message is

rtvs::rmarkdown_publish(blob_id = 2, output format = “pdf_document”, encoding = “cp65001”.
the option encoding = "cp...." varies with different files.

If you have any screenshots demonstrating the issue, please include them as well to help us diagnose it better.

Problem

I usually use rmarkdown to write my statistic analysis report, but I can not compile my rmd file to pdf successfully by RTVS, but it works in R or MRO console when use render() function in rmarkdown package.

Error

Note: I wrote both Chinese and English in my rmarkdown, however, I also fail to compile rmd to pdf in RTVS even if I only write English in rmarkdown.
