Hello, my RStudio has been giving me issues from my keyboard. Whatever I type it will keep the first letter I type be what is shown. For example, If I want to type "hello" it will appear at "hhhhh". This will reset to a different letter approximately after 2 minutes. I have uninstalled base R and R studio, restarted my own computer and nothing has helped. My keyboard is fine everywhere else I type, including in base R. I saw a couple of people have this same question but there were no solutions. As regard to update it says I have the latest version of R studio.
The last thing I remember seeing/happening was when I was typing I saw something appear at the top of my script as "Unicode On" or something similar. I looked up what to do with that and did File > Reopen with Encoding > and have ISO 8859-1 (System Default) on.
