That does not listen on port 5000. I think it means to listen (on next available port) for connections from host 5000 (which would be 0.0.19.136). The proper syntax is nc -l -p 5000.pi4@raspberrypi:~ $ nc -l 5000
There are at least three different implementations of netcat available in Debian, so it is possible your buster system was using a different one.
