If you search on SO you find that the error typically lies in failing to 
properly update R package libraries when you upgrade to a new 
installation of R. So it may not have anything to to do with the pillar 
package specifically.  My understanding (not an expert understanding) is 
that this arises because the serialization protocol of rds files may 
differ from version to version.

You might first follow the usual path of removing any .Rdata and 
.Rhistory files

Then an R console command to try might be:


update.packages(checkBuilt=TRUE, ask=FALSE) # may take a long time
