error using the 'digest' package in R - r

Question

I recently had some problems installing and using the package "digest" in R-3.4.3, which I used previously in R-3.4.1 with no problem. Below are the messages I received from R.
install.packages("digest", dependencies = TRUE)

Error: package or namespace load failed for ‘digest’ in FUN(X[[i]], ...):
no such symbol digest in package E:/R 3.4.3/library/digest/libs/x64/digest.dll
Previously I used install.packages(devtools) in R-3.4.1 which installs "digest" as well, and it all worked fine. Recently work upgraded our operating system to windows 10 (from 7) and installed R-3.4.3 for us, and I couldn't get devtools to work anymore, I figured out it's because digest is not working as has been shown above. I've read everything I can find online, but I have no clue how to fix this.
