R version change [4.0.2 -> 4.0.5] detected when restoring session; search path not restored

Hi,
I am using a Rstudio server account to run our project.
The script was running fine when I left it but when I logged back in after a few hours this appeared

"R version change [4.0.2 -> 4.0.5] detected when restoring session; search path not restored"

And the code I was running in the console was gone.
Can you give me guidance on what I can do? There is not much results when I search online.

Thank you!
