-    If this is a dump, the problem could also be that the dump is missing some memory required by SOS. Try generating a "full" dump (the default with `dotnet-dump collect` without a `--type` option) or add setting the crash dump generation (createdump) environment variable `DOTNET_DbgMiniDumpType=4` (.NET 6 and below require `COMPlus_` prefix instead of `DOTNET_`).
