r studio crashed and not open

Hi there
Just updated the Ubuntu systems 18.04 and reboot, after that, I updated to R version 3.6 and r studio. However, the new release not compatible with virtual box 6. Every time I install virtual box it removes the R and the same for the R. if I installed R and r studio, the r studio not open and it gives the following error message

rstudio
