[RESOLVED] VB6 0xc0000005 on Windows 11 after calling *any* API

[taishan]

Hi gang, I'm using Windows 11 Build 20000 co_release 210604-1628 - Running in Developer Mode, Always run updates, using only Windows Defender for antivirus, excluded my source code folders from scans.

VB6 ran fine on Win11 until VS2005 (seemingly random) started trying to re-install from source media, every time I opened VB6. So I uninstalled VS2005, and VB6 quit working completely. So I uninstalled and reinstalled.

Now, VB6 loads fine (no App Compatibility settings), opens (As Administrator) any project. If you run (F5), the entire IDE disappears. If you step through (F8) it will execute any type of VBA code until it hits an API (doesn't matter - kernel32, user32, custom dlls), either declared or through a type library, and then the IDE disappears.

Windows logs show:

I am out of ideas... help.
