R markdown code chunk not executable after saving

Describe the bug

The code chunk works perfectly before I named and saved the file. The following code, without naming and saving, can be linted and produce the right plot in vs code plot pane. But the same chunk will be no longer executable, and not linted, after I gave the file a name (such as test.Rmd) and saved the file.

To Reproduce

Steps to reproduce the behavior:

1. press ctrl+N, choose file type as .Rmd
2. type in the following code

test <- rnorm(1000)
plot(test)

1. the code chunk was linted and if you run the code chunk, it works perfectly with a plot pane shows up
2. save the file with name “test.Rmd”
3. the lint disappeared, and the code chunk was no longer executable.

Do you want to fix by self? (We hope your help!)

No

Expected behavior I would like the code executable after the .Rmd file is named and saved.

Screenshots when unsaved, everything works fine.

after naming and saving, the code chunk is not executable

Confirmed! It worked on my PC.

Actually I did not touch the .jason files, I have no idea where they came from…

Many thanks!
