Tried running it on the latest LTSC Enterprise build but experienced the same issue as https://github.com/btbd/umap/issues/1. The error occurs on https://github.com/btbd/umap/blob/master/boot/main.c#L142. Both secure boot and fast boot were disabled.

I threw my winload.efi into a disassembler and loaded the provided PDB, but it seems that there is no symbol information for OslExecuteTransition (or any of the other symbols that need to be scanned for this mapper to function) for this build.
