When trying to open a project, you might see `Error: error code 127` and the project cannot be opened.  
You also see an error message like below.

```r
R error: Error in loadNamespace(name) : there is no package called ...

```

This issue tends to happen when you manually installed R packages that conflict with R packages that Exploratory uses under the hood. If you hit this issue, please Reset R Packages by following instruction below.
