Problem with RStudio update

Hi everyone,

I'm running RStudio on a Ubuntu 18.04.6, my R version is 4.3.0 (2023-04-21) -- "Already Tomorrow".
After updating RStudio to the latest version with the installer rstudio-2023.03.1-446-amd64.deb, I am no longer able to run RStudio. Opening it from the GUI doesn't work. When trying to open it from the terminal, I get a pop-up error window (please see the attached capture), plus the following message in the terminal:

[17871:0517/072347.762744:ERROR:gpu_init.cc(523)] Passthrough is not supported, GL is desktop, ANGLE is

To terminate the node process on unhandled promise rejection, use the CLI flag --unhandled-rejections=strict (see Command-line API | Node.js v20.2.0 Documentation). (rejection id: 1)

On the other hand, when trying to open it as admin (sudo rstudio), I get the following:

[0517/073235.866857:FATAL:electron_main_delegate.cc(299)] Running as root without --no-sandbox is not supported. See 638180 - chromium - An open-source project to help move the web forward. - Monorail.
Trace/breakpoint trap

I already tried to uninstall and reinstall. I also tried to install earlier versions of RStudio, but the problem persists.
I need to use RStudio on my daily routine...any advice on how to solve this is highly appreciated .

Thanks.

As the screencap mentions "the R session failed to start", can you try opening R (not Rstudio) directly from the terminal?

Yes, R works fine, here below is what I get by calling it from the terminal:

Any help is appreciated.
