It happen to me first time (I worked on few RStudio servers).
There is a line in ~/.config/rstudio/rstudio-prefs.json:
But after login there is new session created or I am connected to one. It never connect me to existing opened projects.
Is there some other option to change? Conflicts maybe?
As I mention it is first time I see this, on other servers everything is ok.
RStudio 2022.02.3+492.pro3 "Prairie Trillium" Release (35bed28676c261915069832c266ca40f9a8d51e6, 2022-05-26) for CentOS 7

Thread is locked but I found root cause:
I was using some old link saved in browser (it was chrome webpage app, true link is hidden so I take time to find it). The link had some session id in it. When I launch RStudio by the link there were warnings in logs (invalid session scope for user) and it starts with empty new session in home dir. Using basic link https://your.rstudio.server/ works without problem.
