Error in prep_call_sampler(object)

Summary:

We have encountered issues with the Rstan package: a code that worked before with R Platform and still works on personal computer does not work anymore on the platform.

Personal Computer have Rstan package version : '2.18.2' R Platform have Rstan package version : '2.19.2'

could be possible that " Older Version RStan objects in memory break Rstan " (https://github.com/stan-dev/rstan/issues/443) , could be causing this issue ?
