Failed to launch LSP on helix editor

I’m having trouble making Omnisharp work with helix:

2025-08-17T15:15:48.585 helix_lsp::transport [ERROR] omnisharp err <- "Failed to load /usr/lib64/dotnet/shared/Microsoft.NETCore.App/9.0.7/libcoreclr.so, error: libunwind-x86_64.so.8: cannot open shared object file: No such file or directory\n"

It seems to be missing libunwind, but the dependency is actually installed on my Fedora 42:
