Mark ExEventObjectType and IoFileObjectType as DATA exports in Source.def. Without DATA, the import library generates function-style thunks that are only 4-byte aligned on ARM64, but the ARM64 LDR instruction for 8-byte loads requires 8-byte alignment, causing LNK2048 relocation errors. Consumers that reference these symbols without __declspec(dllimport) (e.g. via WDK headers) need /ALTERNATENAME linker flags to resolve the direct references against the __imp_ import symbols.
