Can you open an issue in Cbc.jl please? I likely need to do something similar to Bump version of Clp_jll that we support by odow · Pull Request #133 · jump-dev/Clp.jl · GitHub.
Try add Clp_jll@100.1700.601 in the package manager, then restart Julia.
P.s. hi from Auckland. I’ll fix this tomorrow morning.
