c# project build mapping not showing in Configuration manager (VS2019)

I have several projects without build mapping showing, despite definitions in the project (csproj) file. Using VS2019.

What is happening ? How to correct it ?

"not showing":

With VS2019, nothing is visible and it does not change after operations (using configuration manager, restarting VS2019).

With VS2022, AnyCPU is selected and visible but Configuration Manager does not allow any change (I do the change (creating x64 configuration from AnyCPU as suggested by wenbingeng-MSFT), but without any impact, AnyCPU remains, event after reload and reboot):

Solution

I managed to resolve the problem for one c# .net5+ project stuck at AnyCPU:

this line should be deleted in the project file:

<PlatformTarget>x64</PlatformTarget>

an replaced by:

<Platforms>AnyCPU;x64</Platforms>

After that, I could just select x64 as platform for this project. This shows at least one problem that Configuration Manager could not resolve as it is (17.5.1). This also could help create a minimal repro.
