It could be that you are on stable branch - AUR often requires unstable branch to build correctly.
I think you need to take a walk around the maintainer at AUR.
Cura has a lot of AUR dependencies which you may need to resolve manually.
I get a failed dependency arcus - could be a package got renamed - because I can only find package named libarcus.
Even so - you will only get it to build with some manual intervention.
As I see it you need to resolve these manually
==> Missing dependencies:
-> python-pyqt5
-> python-scipy
-> python-numpy
-> uranium
-> curaengine
-> libsavitar
-> python-pynest2d
-> python-keyring
-> python-trimesh
-> cura-resources-materials

You will get a cascading build failure using the PKGBUILD because
- it depends on the custom uranium script
- which if lagged out-of-date on 2023-05-11
- which in turn depends on arcus
- which in turn does not exist
