error in Rstudio

Greetings,
I tried to open R-studio(windows 10 pro) but instead of running the app, my
screen opens a window saying 'loadlibrary failed with error 1114: some
preparation routine of a DLL failed'
I deleted both R and R-studio, but when I downloaded them again(both in
latest edition), the same thing appears.

Please help me with my problem,
Best Regards,
Kyriakos
