rstudio – How can I solve “R studio session aborted, fatal error”?

My rstudio is occuring this error.
“R session aborted”: R encountered a fatal error. The session was terminated.

I have tried removing and reinstalling the rstudio app from my mac but it didn’t help.

Also, I googled and found out that libraries may occur this error. So, I tried to find my r library path using .libPaths() function in R. However, I could not. Because I can’t enter any function because it’s keep occuring errors.

Does anybody have same problem?

If you have any solution to this “fatal error”, please help!
If you know how I can find the r library path without using R studio, please share.
