No response checking for R Studio Updates

I am running RStudio version 1.1.453. I noticed that after updating R to version to 4.1.0, there are some impacts to RStudio (for example, plots appear in a pop-out R Graphics Active Device window rather than in the IDE). Articles I read suggest that I should update RStudio, but I get no response from RStudio when selecting "Help" > "Check for Updates". Any idea what is wrong here, or how to get RStudio updated?

Thanks,

I suspect you are using a 32-bit system, if that is the case, newer versions are not compatible with that architecture, if that is not the case, then you can manually download the latest version from here
