RStudio attempts to load 'required' package but package not listed in any open scripts

Every time I open R Studio I get a the following message:

Loading required package: RMariaDB
Error in .requirePackage(package) :
unable to find required package ‘RMariaDB’
In addition: Warning message:
In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE, :
there is no package called ‘RMariaDB’

But in my current open scripts the RMariaDB package is not used. I only have one script which uses the RMariaDB package. So I don't understand why R and R Studio thinks that RMariaDB is required every time I open the program. Is there a way to silence this message?

Does resetting RStudio's state get rid of the message?
