Please can someone assist with Exception analysis? - exception

Question

I've built an application - it works on my development server, and the development test device paired with it.
I've then published the application to test on another set of virtual machines with more diversity in the Operating Systems, and the application only works on one device - I have no idea why.

---------
All I can see here is that ntdll.dll is triggering a breakpoint exception. Googling that has yielded no results that help me understand what's happening here.
My application is published using .NET 6.0 as a self-contained file.
Each of the class libraries associated with it are all published using the same framework and build targets (.NET Core 6.0, Windows, 7.0)
I've tried both a x64 instance and x86 instance - both yield the same results.
My development virtual machines are:
Windows Server 2019 - 17763.3887
.NET Runtime 6.0
Desktop Runtime 6.0
Windows 10 SDK
Windows 10 - 18363.2274
.NET Runtime 6.0
Desktop Runtime 6.0
My test machines are:
(WORKING)
Windows Server 2019 - 17763.3887
C++ Redists (various)
Visual Studio Tools for Application 2017 (no idea what this provides, but its the only thing that I could see might make the application work)
(NOT WORKING)
Windows 10 - 19044.2546
.NET Runtime 6.0
Desktop Runtime 6.0
Windows 11 - 22000.1516
Visual Studio Tools for Application 2017
Windows Server 2016 - 14393.5648
C++ Redists (same as 2019 server)
Windows Server 2012R2 - 9600
.NET Runtime 6.0
Desktop Runtime 6.0
So I've tried a different combination of what I guessed might be prerequisites that the application might need to launch (even though its self-contained and huge) but still no luck, and I'm struggling to identify why the application just crashes with stuff external to my application.
I previously had a stack-overflow response, but now all I get is a breakpoint.
