I installed an update to R studio today and readxl and readr will no longer read excel and .csv files. The error message says " Is this a valid excel file? could not find file ".rs.digest"

What version of RStudio do you have?

Yes, this is a bug in the latest release (2026.05.0), and we are working on a patch release (2026.05.1) to fix this. Tracking issue: "Import Dataset" can't import csv · Issue #17777 · rstudio/rstudio · GitHub

I get this too ... but if I dismiss the error message and click the "Import" button, the file does import.

Thanks for reporting this. It's helpful to have the specific error message here, especially since the team confirmed it's a bug in the 2026.05.0 release. I'll be keeping an eye out for that 2026.05.1 patch.

You can give a daily build a try (e.g. 2026.05.1+225), it includes this fix and a few others.

This isn't currently an official release but the only changes from the official release are some targeted bug fixes per rstudio/version/news/os/NEWS-2026.05.1-golden-wattle.md at rel-golden-wattle · rstudio/rstudio · GitHub.
