Your error message is too short. Please post the full error message, including the command that you executed to get it. Please copy paste the error message in code blocks.

I see some feedback was already given here:

Try remove the file /etc/dnf/libdnf5-plugins/00-systemd-inhibit.conf. The file belongs to the package libdnf5-plugin-systemd-inhibit.

If that makes dnf work again, you can either re-install that package or un-install it.
