After dwarves update, I can't anymore boot custome builded kernels

Here https://docs.fedoraproject.org/en-US/quick-docs/kernel-build-custom/ is described how to build a custom kernel for testing patches and bisecting.

Usually I run this sequence of commands:
1) For building
make clean && make -j32 bzImage && make -j32 modules
2) For installing
sudo make modules_install && sudo make install

With dwarves-1.29-1.fc42.x86_64 the builded kernel always unbootable; instead, the kernel stuck with the messages "failed to validate module ..."

The last workable version of dwarves is 1.27-3.fc42

Reproducible: Always

This bug appears to have been reported against 'rawhide' during the Fedora Linux 42 development cycle.
Changing version to 42.
