Interpreter details:

R 4.4

Describe the issue:

Exposing internal errors via console after running another command

Steps to reproduce the issue:

R script:

View(data.frame(string = c("catfish", "cattails", "dogwood", "catapult")))

1. Read that dataframe into Data Explorer.
2. Try to apply a "does not contain 'cat'" regex ^(?!.*x).*
3. Note the error in the filter since it's not valid for R.

4. Apply a R compliant regex for the same thing ^[^x]*$ - note that it filters all of the values except dogwood.
5. Run any command in R console (head(mtcars)).
6. Note the error in the console

Warning message:
In grepl(pattern = params$term, col, ignore.case = !params$case_sensitive) :
  TRE pattern compilation error 'Invalid regexp'

Expected or desired behavior:

An invalid regex shouldn't be exposed via console.

Were there any error messages in the UI, Output panel, or Developer Tools console?
