Trouble upgrading 22.05.3 to 23.05.2 on Belkin RT3200

I used the LuCI Attended Sysupgrade package to request new firmware for my Belkin RT3200 router. I used all the default options, and after it got to the "Building firmware" stage, I saw this message.

What other troubleshooting information could I provide? How could I proceed? Many thanks!

Start by reproducing the request against https://sysupgrade.openwrt.org with the listed profile and package set. Inspect the imagebuilder failure around Makefile:189, Makefile:154, the missing LuCI translation packages, and the libustream file clash; done means the requested firmware image builds successfully.
