Import Dataset functionality in the Environment tab not working



I am trying to import a dataset using the "Import Dataset" option in the Environment tab. Every file that I try to import states that there is "No data available in table". This is occurring for all .csv and .xlsx files that I am trying. Up until this morning this functionality was working properly. Also, the files that I am attempting to import are not corrupted and when I open them in Excel show the data correctly.

Below packages are loaded.

System Information:

  • [Default] [64-bit] C:\Program Files\R\R-3.4.4
