Studio can't read the tutorial

hi ,
Im a bit frustrated since I couldn't read my tutorials on RStudio, though I run the codes correctly and console has no problem but at the time I press the button for RStudio tutorials (right corner) it keeps loading the whole time and on the background job said "Execution halted". So , I hope anyone could help me to overcome this issue

What OS and version of Rsdudio?

Can you post the output of

sessionInfo()

here ?

Thanks.
