Continuing the discussion from [Why does the `'Mesh' object layout differ from` `mesh.create_unit_square`?](https://fenicsproject.discourse.group/t/why-does-the-mesh-object-layout-differ-from-mesh-create-unit-square/12327):

I just want to report that many tests fail when building the Basix, UFL, FFCX & DOLFINx stack (see [this link](https://file.io/l6m18ozgxaIF) or [this copy](https://anonsharing.com/ea4a580a0eb39d0b), and below). It may have to do with Pyhon 3.11 (see related discussion). Should I be concerned?

You’ve cut your error log short. Does it not report what the actual error was? (should be 2 of them)

Hi, no, I didn’t cut it short. That is all that I get.

By the way, the links are not the same as the log shown here. You may also want to look at those.
