title: lazy-load database '../R/NymbulCredentials.rdb' is corrupt
body: <p>I am trying to install a package from GitHub in support of deploying an app to shinyapps.io. If I download the package onto my machine, then it installs without issue.  However, if I execute the command (in RStudio):</p>
  
  <pre><code>devtools::install_github(repo="rlmoore0/NMDeploy", subdir="NymbulCredentials")
  </code></pre>
  
  <p>then I get an error message:  <strong>Error in (function (n)  : 
    lazy-load database '../R/NymbulCredentials.rdb' is corrupt</strong></p>
  
  <p>This GitHub repo is public, so anyone can try running this command from within R/RStudio with devtools installed.  I am on a Windows box running R 3.6.3, Win10.</p>
  
  <p>Any suggestions?</p>
  
  <p>I have looked at questions from other people with similar problems and based on the responses to them, I have tried:</p>
  
  <ul>
  <li>Closing and restarting R/RStudio</li>
  <li>Executing the command <code>devtools::unload("NymbulCredentials")</code></li>
  <li>Executing the command <code>unloadNamespace("NymbulCredentials")</code></li>
  <li>Removing the installation library the package is being installed to as referenced by <code>.libPaths()</code> and trying a fresh directory as the installation location.</li>
  </ul>
  
  <p>The error still persists.  </p>
