Rstudio new version doesn`t work correctly

I have tried to delete R and Rstudio and download again. But it didn`t help.
What can be the reason of this strange behavior?

Have you tried changing to software rendering?, you can change it by holding the Ctrl key while opening RStudio, then you should see this menu and change the "Rendering Engine" to "Software".

Thank you!!!
You`ve been very helpfull.
