Error in detach("package:rlang") : invalid 'name' argument

Hi all,

When I start R Studio, I recieve the following info:

R version 4.3.1 (2023-06-16 ucrt) -- "Beagle Scouts"

Error in detach("package:rlang") : invalid 'name' argument

It is the last line, with "Error in detach()" that seems to disable Rmarkdown and kniting for me.
I have tried the most simple codes that you can have, but when I try to knit the code, I get the following error message in the Render output console:

"Error in detach("package:rlang") : invalid 'name' argument
Execution halted"

I have removed rlang and reinstalled it, I have removed all packages and Rstudio/R and reinstalled it. All packages are updated.

The following regarding sessionInfo():

When starting RStudio, only "compiler_4.3.1 and tool_4.3.1 are loaded via a namespace

If there are any Suggestions to what can cause this error, or what steps to take please let me know!

Sorry in advance if there is something wrong with the formatting!

After further looking into the issues, I removed R, RStudio and RTools and all folders assiciated with the programs. Found a helpful post HERE and followed it!

Maybe this can help someone else!
