Can you enable logging with logging enable? Do commands like runtimes, sosstatus or dumpheap -stat work? It is almost like x64 version of libsos.dylib is being loaded (the one under osx-x64 instead of osx-arm64). The only way I could see that happening is if the SDK/runtime installed is x64 instead of arm64. Can you make sure the right runtime architecture is installed? dotnet --info should display that. You might have to reinstall the SDK and then dotnet-dump.

You were right. I did have x64 sdk installed for whatever reason. I deleted everything and it is better.

Any thoughts on the GetFrameContext failed: 80070057 @mikem8361 ? It would be really nice to get stack and dump objects.

[hoyosjs]

That's probably dotnet/runtime#104816 - a relatively recent regression under investigation that was caused by dotnet/runtime@9528c15 this is .NET 8, so my point is moot.

[mikem8361]

Sorry, I didn't actually look at the clrstack output. I saw that you said everything was ok and stopped reading.

[mikem8361]

I think we need a M3 to repro this.

[mikem8361]

@wfurt would you mind trying the latest dotnet-dump version to see if this still repros?

You can install the latest preview like this:

dotnet tool update -g dotnet-dump --add-source https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet-tools/nuget/v3/index.json
