Crash log when launching Bonsai main editor or package manager

Hi there, and thank you for all the amazing work on Wine!

I'm a relatively new user and have encountered an issue when running a Windows
application called Bonsai-Rx under Wine. Bonsai-Rx is a C#/.NET-based
application widely used in neuroscience research. Traditionally, Bonsai running
on Linux has relied on Mono, but I’m exploring the possibility of running
Bonsai using Wine instead.

System Details:
Wine version: Built from source (latest master, 10.7) using Shared-WoW64
instructions
Bonsai version: Installed from official site (latest, 2.8.5):
https://bonsai-rx.org/docs/articles/installation.html
Wine prefix setup: .NET Framework 4.8 installed via winetricks -q dotnet48
System: Ubuntu 24.04, x86_64, kernel 6.8.0-59-generic

The Issue:
Bonsai installs and launches correctly. The welcome menu displays, but
selecting any option that would launch the main editor window or the package
manager (e.g., New File, Open File, Manage Packages, etc.) causes the
application to crash due to an assertion in the function:

`TREEVIEW_DoSelectItem(TREEVIEW_INFO *infoPtr, INT action, HTREEITEM newSelect,
INT cause)`

Observations:
If I comment out the assertion line in the above function and rebuild Wine,
Bonsai functionality works as expected.

I’ve tested several native DLL overrides (comctl32, comdlg32, vcrun6) without
success.

The issue persists in multiple Wine versions (10.3 through 10.7).

Questions:
What are the implications of removing this assertion in TREEVIEW_DoSelectItem?

Could this point to a misbehaviour in Bonsai, or is it a Wine edge case that
should be handled more gracefully?

Is there a better workaround or fix for ensuring compatibility with this
application?

I’ve attached the full error stack trace for reference. Any guidance or
insights would be greatly appreciated.

Thanks again for your time and your excellent work!
