Anyone else get this error today after updating?
installing protobuf (35.1-1.1) breaks dependency ‘libprotobuf.so=35.0.0-64’ required by libphonenumber
I just came here today to look for this issue as well. You’re not alone.
In order to discount various problems it may be helpful to include more of the output.
( For all we know it coud be yet another example of users breaking their repositories in pacman.conf )
But assuming all is well then it could just be a case of needing to sort mirrors and/or simply waiting a bit.
Further investigation it appears as though libphone number is required by Evolution. When trying to update, here is the output:

Waiting a bit worked, thanks!
cachyos-rate-mirrors prioritizes the CDN77 mirror at archlinux.cachyos.org (CachyOS-PKGBUILDS/cachyos-rate-mirrors/cachyos-rate-mirrors#L148). That mirror is stale for me:
> date -d @(curl https://archlinux.cachyos.org/repo/lastsync)

which creates several conflicts between outdated packages in extra and updated dependencies in cachyos-extra-*.
Yeah, that is one of the reasons I do not much care for cachyos-rate-mirrors.
I did write another one that you may opt to use instead;
