CI build, that uses older msys2 version, fails. That's easy to fix.

But the snapshot contains xz version that is affected by CVE-2024-3094 backdoor exploit, and for that reason I want to create a completely new snapshot (even though the nature of the backdoor is such that it would never be active in our build)

These fixed.
