Collected errors:

• check_data_file_clashes: Package libustream-mbedtls20201210 wants to install file /builder/build_dir/target-arm_cortex-a7+neon-vfpv4_musl_eabi/root-ipq40xx/lib/libustream-ssl.so
  But that file is already provided by package * libustream-wolfssl20201210
• opkg_install_cmd: Cannot install package luci-ssl.
  make[2]: *** [Makefile:189: package_install] Error 255
  make[1]: *** [Makefile:154: _call_manifest] Error 2
  make: *** [Makefile:274: manifest] Error 2

Start with the reported ASU request data and the package-installation log, focusing on the conflict between libustream-mbedtls20201210 and libustream-wolfssl20201210 while installing luci-ssl. Reproduce the Fritz!Box 4040 image request against the stated 23.05.0 target; done means the requested firmware image builds without the package-selection error.
