The first one
CSC : warning CS8784: Generator 'VtableIndexStubGenerator' failed to initialize.is used for COM and only used in CI so will not cause any issues.The second one
CSC : warning CS8784: Generator 'LibraryImportGenerator' failed to initialize.Would be an issue if you used custom marshallers or anything with[LibraryImport]in user code.It maybe that this might be because the versions of the native-aot-llvm compiler are miss matched with the .net version you are using, i.e. the .NET SDK version used is 8 and the native-aot-llvm is build against 9 (or now 10)
