You can run them through c++filt to see the unmangled name:
$ echo _ZN7QObject5eventEP6QEvent | c++filt
QObject::event(QEvent*)
Given that QObject::event is available in Qt5,[1] it sounds like the
libQt5Core.so.5 link library is missing from your path.
I have a Ubuntu machine handy (and not a Debian machine). In Ubuntu,
the package that provides libQt5Core.so.5 is libqt5core5a:
$ dpkg -S libQt5Core.so.5
libqt5core5a:amd64: /usr/lib/x86_64-linux-gnu/libQt5Core.so.5.15
libqt5core5a:amd64: /usr/lib/x86_64-linux-gnu/libQt5Core.so.5
libqt5core5a:amd64: /usr/lib/x86_64-linux-gnu/libQt5Core.so.5.15.3
It looks like Debian provides the libqt5core5a package. See
https://packages.debian.org/bookworm/libqt5core5a
Is libqt5core5a installed?
