Seems unlikely that Rstudio would generate an error message about R code. It's just  a shell around the R interpreter.

I do not see the word "key" in any of the error messages from stats::fisher.test. Error message do not generally use the word "bug" either. You should post the exact error message copied from the console display,

What is needed is the exact code used and some sort of effort at delivering a reproducible example. The function fisher.test is most likely not from the gmodels package but rather from the stats-package. You should be able to see this by typing this at the console:

# when I do this  I see `<environment: namespace:stats>` as the last line
# ... and there is no fisher.test in the gmodels Index page

Please read the Posting Guide and see if you can respond with a reproducible example. Postings to Rhelp should be in plain text, since postings in HTML are likely to be corrupted.
