I believe you installed a WiFi driver module (rtl8821cu) manually.

You need to find a version that is compatible with the new 6.x kernel 
series. I don't think that this module was provided by Debian so we 
can't help much here.

Note that this is the LTS support list, i.e. support for Debian 11 
bullseye. For Debian 12 bookworm support, see https://www.debian.org/support
