depends on your kernel version

uname -r
6.12.25+rpt-rpi-v8

should work, if not you can switch SD card back to RPi4

You can also install the RPi 5 only 16k page size kernel with dietpi-config > Advanced Options > RPi kernel choice. But as Joulinar said, the v8 kernel supports the RPi 5 as well, so you can also do that afterwards on the RPi 5, and then remove the v8 kernel in the same turn. The menu shows you which kernel supports which RPi model.
