I have just installed the R essentials from Anaconda (having R already installed on my computer) in order to use R in Jupyter.
Now, when I open a new R notebook in Jupyter, after few seconds (without even typing anything) the kernel crashes and needs to be restarted.
The error I get on the terminal is
[I 12:30:36.297 NotebookApp] Kernel started: dd5dd612-2c8f-4235-9619-1cf5a46b3e89

I guess it might be a problem with shared libraries but I can't figure out how to solve it...

Try disabling any browser extensions and/or any Jupyter extensions you have installed. Some internet security software can interfere with Jupyter. If you have security software, try turning it off temporarily, and look in the settings for a more long-term solution.
The Jupyter Notebook is a Web application which permits to create live code in different languages. Usually, developers exploit the Jupyter Notebook to write code in Python. However, Jupyter also supports other programming languages, including Java, R, Julia, Matlab, Octave, Scheme, Processing, Scala and many others.
As we get more kernels for Jupyter in VS Code, i believe we could end up with more kernels that require the ability to restart a kernel. Basically the kernel restart is used to kill the old dead/hung/unusable kernel and start with a whole new kernel (with new state).
(TEMP FIX ONLY)

I was able to get my kernel running using the suggested temporary fix:
$ conda remove gcc libgcc
