I'm a bit confused on what to do here, the issue in the OP still exists so I
don't really understand why this would be closed:
``` r
packageVersion("arrow")
#> [1] '23.0.0.1'
file_location <- tempfile(fileext = ".csv")
test <- data.frame(x = 1, x = 2, check.names = FALSE)
write.csv(test, file_location)
readr::read_csv(file_location)
#> New names:
#> Rows: 1 Columns: 3

#> ℹ Use `spec()` to retrieve the full column specification for this data. ℹ
#> Specify the column types or set `show_col_types = FALSE` to quiet this
message.
