R session doesn't respond to any code I run in Rstudio

[yifanliu]

Hi there,

I've encountered a bug today that I've seen in the forum, but strangely most reported in R ver. 4.2, while mine in 4.1.3.

After dealing with a big task, the IDE turned slow, and I restarted the computer. Then the problem showed up as described in my title, session panel seemed to freeze, but when I checked the task management. CPU usage of R session is relatively high, and memory consumption is even slowly growing.

But when I open R GUI or other IDE (VS Code for example), nothing happened, and R code runs smoothly.

I've tried uninstalling and reinstalling the R / Rtools / Rstudio and reboot the system more than once, but it does no help.

My session info is as follows. I get se session info in vs code, don't if it helps:

Thanks in advance for any help to provide.

supplementation:
I wait the Rstudio for about 10 minutes, and it unfreezes, but the Qt_webengine takes nearly 1 Gig of memory.

I then restarted the session, and the problem still disappear. But when I relaunched Rstudio, the problem showed again.

Have you tried resetting RStudio's state?

Resetting RStudio Desktop's State

Does this happen when you are on a specific project? Are you restoring your previous environment on startup?

thanks @andresrcs! I reset the state and it worked.
I didn't use Rproject today, and not restoring anything, so the problem is quite puzzling me.
