If I’m understanding this correctly, some lib32 packages have been completely dropped due to a vulnerability:
https://vulners.com/cve/CVE-2026-3099
And I imagine they’ll remain that way until fixed. What you can do while waiting for that to resolve itself is use a different Wine/Proton.
proton-cachyos-slr should avoid the affected packages. And so should wine-cachyos. Alternatively, you can use other Wine versions found elsewhere, like GE’s Proton.
But cachyos-gaming-meta and proton-cachyos look like they’re out of commission for now until those lib32 issues are resolved.
