I have a problem when trying to save a new R script in RStudio. When saving a new file, the save as bar (the part with which you choose the file type to save as) is greyed out and I cannot select a file type to save as. I was able to save normally until, I was suddenly unable to save. I am still able to save scripts that I have created, but newly created scripts are unable to be renamed.
I am currently using R version 3.5.0, RStudio version 1.1.453 (open source), and running on a Windows 10 system.
I have found this older post that relates to a similar issue, but it does not have any conclusive information on how to solve the problem.
I have tried saving with .R as suggested in the above post, but this will not allow me to run the scripts once saved. I have also attempted uninstalling and reinstalling both RStudio and R itself, but this caused no change.
I have no idea why this is happening and any help in figuring out if this is a bug or something that can be easily fixed is greatly appreciated.
