See: https://autobuilder.yoctoproject.org/typhoon/#/builders/117/builds/4399 mesonpy has been added to oe-core as it's declared the build backend for new versions of numpy. However, after making python3-numpy inherit the new backend, reproducibility issues were detected. This should be fixed ASAP so that we can continue using the latest versions of python3-numpy.
This has been fixed for a while (not seeing it anymore), but not sure exactly when that was.
