BadImageFormatException when creating installer with VisualStudio 2019

hope you are doing great.

I am trying to create an installer for my project (a modified MissionPlanner, for those who know that open source software) with VisualStudio 2019. I am doing it with the setup project of Visual Studio. I managed to create an installer, and install the software on my computer. However, when I try to use my application, I have the error

INFO MissionPlanner.Program - ******************* Logging Configured

I've read across the internet and all the similar topics that this is problem between 32 bits and 64 bits. However, I think I have tried pretty much everything, but it still does not work. What I tried :

1. • Compile in "Any CPU" mode in the configuration manager
   • Right click on the project and "Properties" then "Target Platform" to Any CPU
   • Right click on the project and "Properties" then Uncheck "Prefer 32 bits"
2. • Compile in "Any CPU" mode in the configuration manager
   • Right click on the project and "Properties" then "Target Platform" to Any CPU
   • Right click on the project and "Properties" then Check "Prefer 32 bits"
3. • Compile in "x64" mode in the configuration manager
   • Right click on the project and "Properties" then "Target Platform" to x64
   • Right click on the project and "Properties" then Uncheck "Prefer 32 bits"
   • Click on the Setup project properties window then target "x64"
4. • Compile in "x86" mode in the configuration manager
   • Right click on the project and "Properties" then "Target Platform" to x86
   • Right click on the project and "Properties" then Uncheck "Prefer 32 bits"
   • Click on the setup project then properties window then target "x86"
5. • Compile in "x86" mode in the configuration manager
   • Right click on the project and "Properties" then "Target Platform" to x86
   • Right click on the project and "Properties" then Check "Prefer 32 bits"
   • Click on the setup project then properties window then target "x86"

I really don't know what I'm doing wrong, and what I should do in order for this to work, I really need your help !

Thank you
