I tried to create a new project in an existing directory. The files were created, but RStudio immediately showed an error code, and since then every time I open RStudio it shows the same error.
[errormsg=Error in .Call("rs_rstudioReleaseName", PACKAGE = "(embedding)"): "rs_rstudioReleaseName" not available for .Call() for package "(embedding)"
Attempted steps taken to fix:
I have restored my latest git commit (removing the project I had attempted to create). I have reset RStudio Desktop's state, as described in https://support.rstudio.com/hc/en-us/articles/200534577-Resetting-RStudio-s-State.
