OK, then you need to keep reading. Instead of simply installing R 4.0.0 you 
need to remove the packages depending on r-api-35 as detailed in

https://cran.r-project.org/bin/linux/debian/#debian-bullseye-testing

The reason is that the backported r-cran-* packages have a lower version 
number than the r-cran-* packages in the Debian archive, but the packages in 
the Debian archive depend on r-api-35 while the new backport provides r-
api-40.

Also, you will need to rebuild all locally installed packages as detailed on 
the CRAN Debian page.

Greetings,

Johannes
