Error using C++/CLI dll in Azure function (zip deployed) - dll

Question

So I have:
a c++/cli wrapper withini a clr c++ dll
a c# net6 azure function which is referencing the c++/cli project
The issue:
It works perfectly when I'm testing it in local (with visual studio)
When it's published (zip) on Azure I can call functions that don't use the c++/cli dll,
but when I'm calling (via Test/Run button) a function that use my c++/cli lib
I have this error code 500 Internal Server Error and this error message:
Could not load file or assembly 'C:\home\site\wwwroot\bin\MyCliDll.dll'. Format of the executable (.exe) or library (.dll) is invalid.
I have try a lot of different publishing configuration but non of them worked.
at this point I don't have any idea of what to change i order to make it works, is it a compatibility problem between my c++ and Azure ?
In case, here both of my setup:

Ok I feel a bit dumb I just needed to go to the portal Azure in Configuration->General Settings->Platform and set it to 64 bit...
