On newer releases of some Linux distros (namely Arch), libdl can no longer be loaded correctly, so any library relying on this fails to load (including Veldrid).
I believe a fix for this issue has been found, although I am not the one who found it, however I believe the libdl.so needs to be renamed to libdl.so.2.
I've linked this issue to them so hopefully they can explain the issue a bit better if necessary.
