Error on opening RStudio

[sbgraves237]

When RStuio opens, it says, "Error in .rs.parsePackageDependencies(contents, extension) : object 'partition_yaml_front_matter' not found". I seem to have the latest RStudio, R and all contributed packages. See below.

See Error in .rs.parsePackageDependencies(contents, extension) : object 'partition_yaml_front_matter' not found after update to R 4.2.1 · Issue #11552 · rstudio/rstudio · GitHub as suggested by @HanOostdijk in another thread.

Try closing RStudio, deleting the file .Rproj.user in the home directory, and restarting.

Worked for me, anyway.

Try opening several Rmd files, quit R and then relaunch. Does the message reappear? The number of times the message appears for me is the number of open files minus one. I can get it to stop by disabling Tools > Global Options > Code > Diagnostics > Prompt to install missing R packages discovered in R source files.
