Error in install.packages : cannot open file...No such file or directory

[MaxKerney]

I've encountered this type of error when trying to install certain packages:

Error in install.packages : cannot open file 'C:/Users/PATH TO .CHECKPOINT FOLDER/.checkpoint/2020-04-01/lib/x86_64-w64-mingw32/3.6.3/file143453a1636a/rmarkdown/rmd/ioslides/ioslides-13.5.1/fonts/OpenSansSemiboldItalic.ttf': No such file or directory

I've noticed that the packages that I get this error with all have a string similar to file143453a1636a as part of the filepath. I've tried with the packages Rcpp, BM, and rmarkdown. These packages install fine outside of checkpoint, so I think it must be something going on with checkpoint or MRAN. The issue persists whether I use the latest CRAN release of checkpoint or v0.9.9.9, or R versions 3.6.3 or 4.0.2.

I'd be grateful for any guidance.
