Cannot automatically open pdf file with sumatra when using r-studio

I installed rstudio at c-drive root in win11 home version.

When I knitr my R markdown file, it can not automatically open pdf files while I used
"knit: pagedown::chrome_print" to output pdf files.

The output html and pdf files created correctly.

I've checked that "sumatra.exe" is there under the correct path.

And I found if I used the old rstudio Version 1.2.5042 it worked fine, but it cannot after that until now.

So how can I fix it ?
