So I have a good news, 6.3-rc1 which dev.2023.03.20a is based on, fails, while 6.3-rc3 works. I haven't got further yet and am not sure it's useful to dig further given that it's an already fixed problem that is not related to the patches in your branch. I don't know if you usually rebase on more recent tags though.
