Rstudio debugging info

I was running some code and I encountered an error, I was given the usual two options: Show traceback and Rerun with Debug. I pressed Rerun with Debug.

The problem is each time I run the same code I'm not given the option, it just reruns with debug. I think it flagged a base R function?

Error in `$<-.data.frame`(`*tmp*`, "rate_imm", value = list(lambda_l = 1.21796998183709,  : 
  replacement has 1 row, data has 2

I've restarted the R session and tried the same code on different Rstudio projects. It will always run the same Rerun with Debug. Is there a way to clear this setting? I deleted .Rproj.user but this wasn't enough.
