### Description

Using libsos on a Mac Catalyst app (built with CoreCLR) fails with:

> Failed to load data access module, 0x80004002

To repro, install .NET 11 preview 5 and:

```shell
dotnet workload install maccatalyst
mkdir sos-maccatalyst
cd sos-maccatalyst
dotnet new maccatalyst
dotnet build
lldb -- bin/Debug/net11.0-maccatalyst/maccatalyst-arm64/sos-maccatalyst.app/Contents/MacOS/sos-maccatalyst
(lldb) plugin load /Users/rolf/.dotnet/sos/libsosplugin.dylib
(lldb) run
(lldb)
(lldb) clrstack
Failed to load data access module, 0x80004002
Can not load or initialize libmscordaccore.dylib. The target runtime may not be initialized.

### Regression?

Probably not, because building Mac Catalyst apps with CoreCLR is new.

### Other information

Terminal log: https://gist.github.com/rolfbjarne/b456aef303c25012f0b320a463e19345

App bundle: [sos-maccatalyst-dotnet-diagnostics-5912.zip](https://onedrive.cloud.microsoft/:u:/a@d4ap3hl2/S/IQAB2PXOQ1WySacjQjW6oHQ3AcEE1Y_ikLiLS3YcoBlquvM?e=Yxz8B3)

Start with the provided Mac Catalyst reproducer: install the listed .NET 11 preview and maccatalyst workload, build the app, then load libsosplugin.dylib in lldb and run sosstat followed by clrstack. Trace the data access module loading for the bundled libmscordaccore.dylib; done means clrstack initializes and displays the managed stack instead of reporting 0x80004002.
