When I try to open Rstudio in my browser I get the spinning gif and after a while a popup telling me that RStudio is taking a long time to open. The popup gives me an option to terminate the session or wait. If I choose terminate nothing happens, the gif keeps spinning and I get the same message again.
Other posts on SO suggests deleting files like .RData. I searched my home directory and there is no .RData file (I typically don't save my workspace).
I'm not sure if there are other directories I can look in to delete. In the temrinal from my home directory if I type ls -la I see:

I sometimes navigate to directory rscripts from within r (the last session I was working in was in this directory). When I ls -la from there I see:
drwxrwxr-x 3 myname myname 4096 Aug 27 10:41 .

These are just some scripts I've been working on.
With a Google search I found a reference to directory .rstudio containing session data. Here are the contents of .rstudio:

I'm tempted to start deleting files and directories but am concerned about buckling RStudio. I'm not concerned about retrieving data from my last session.
Is there a directory somewhere where I can delete files from my previous session and have RStudio not try to load my previous session?
Tried deleting cookies and signing in from another browser too, no success
In the terminal when I go top > 1 I don't see any rstudio or rsession related process' running either
Another piece of information that may or may not be relevant. When this issue started I was in the middle of running a dopar loop using 14 of 15 cores. My understanding is that each core creates a new session. As it was taking longer than usual I tried to cancel the operation using the red stop button. Ever since I have not been able to access Rstudio
Our system administrator had to restart RStudio and I was able to connect again. Would like to know what triggered this and if it's avoidable, or if there's a way to rectify without restart. I was told to try brute force if it happens again with
sudo shutdown -r now
