Error in exists(cacheKey, where = .rs.WorkingDataEnv, inherits = FALSE) : 
  invalid first argument

I used the rm() function in R to delete a couple of data frames. They were successfully deleted. However, this prompt kept popping up anytime I ran a new code.

I faced the same error today. For me, it was fixed after restarting Rstudio. You could simply restart by clicking on Session -> Restart R in the top bar. After that, I was able to run my code again without any error.

This seems to be a problem with the IDE (R-Studio). I was able to solve the problem after updating R-Studio to the latest build: 2023.06 Mountain Hydrangea, in the link below:

    The fix starts with build 2023.06.1+437, so you shouldn't have problem beyond that version number.

Closing and reopening the script worked for me.
