Hmm. 'time' is in package stats, and you seem to have saved an object
that is pulling in the namespace 'tseries'.
Loading the workspace is done before loading the standard set of packages.
This appears to be a bug in tseries, for if its namespace needs 'time', it
should import it from 'stats', and it is not even depending on 'stats'.
I can confirm that:
gannet% env R_DEFAULT_PACKAGES=NULL R
Error: object 'time' not found whilst loading namespace 'tseries'
That is a matter for the 'tseries' maintainer (Cc:ed here). If you
try library(tseries) at that point you find
Loading required package: zoo
Error: object 'aggregate' not found whilst loading namespace 'zoo'
Error: package 'zoo' could not be loaded
so package zoo has a similar problem (maintainer Cc:ed).
What can you do? The simplest is to rename the workspace and load()
afterwards as you have done. But before saving, remove any objects which
have a dependence on tseries.

R does NOT crash. It is objecting (correctly) to your saved workspace.
Please see the posting guide, which specifically asked you not to abuse
