Package ‘digest’ was installed by an R version with different internals; it needs to be reinstalled for use with this R version Execution halted

shiny-server

#1

when I try to connect to my app on my shiny server, this message above popped up (package ‘digest’ was installed by an R version with different internals; it needs to be reinstalled for use with this R version
Execution halted) in the log file.

I have tried to install the package again in R on the host machine of the shiny server, but the error remains the same.

Who can help here?

Thanks in advance!
