Warning messages: 1: In readChar(file, size, TRUE) : truncating string with embedded nuls

Dear list members,

I updated to R 4.0 and my MacOS is Catalina 10.15.4.

When using several functions I receive this warning message

It could be loading a library, reading a file, or other tasks.

library(tidyverse)

Warning messages:
1: In readChar(file, size, TRUE) : truncating string with embedded nuls
2: In readChar(file, size, TRUE) : truncating string with embedded nuls

Any idea why is the warning message?

Manuel
