Calling Native function within a custom list class' GetEnumerator breaks results view

## Environment data
1. Windows 10: NET6, NET7
2. VS Community 2022 (latest)
3. VSCode (latest)
4. Omnisharp 1.25, 1.25.1beta

## OmniSharp log
Debug log within zip

## Steps to reproduce
Use VSCode project within zip and simply breakpoint past the list variable in Main as shown in the jpg.

## Expected behavior
Debugger variable results view of class correctly expands instead of failing

## Actual behavior
Debugger variable results view fails to enumerate custom list class' items

## Additional context
My usage scenario would be to call native functions within the GetEnumerator method. The zip project reproduces the issue with a bare minimum example.

Tested with all combinations in the environmental data. Basically the exact same failure was observed across all configurations.
