Did you try !lto in options?

I reverted makepkg.conf (minor adjustments), also provided enough disk space for temporary build (more than 3 GB!?). Still got the same error - I think I might open a ticket on codeberg.

Your makepkg.conf file might be at fault. Try reverting to the default one from Arch. If it fails then try adding !lto in the options=() array in PKGBUILD.

Thx, checksum is fixed.

Still got an error after compilation of the crates has finished. Excerpt:

Try again please. The upstream seems to caused the change of checksums

Weird… I’ll trigger another build
