Error upon opening R "ERROR r error 4 (error readRDS(nsinfoFilePath): unknown input format

[CoralKiwis]

Hello lovely people, can someone help me? Randomly Rstudio didnt open, instead showing this error message. Yesterday was working just fine and i already try to unistall and reinstall multiple times.

I wish i could send more info to locate the problem, but i really dont know. This is my first time using R :(

My best guess is that one of your installed packages was unexpectedly corrupted -- you might need to uninstall or reinstall one or more of your installed R packages.
