I am working with UE5.5. I am using the latest MSVC v143 and the latest C++ v14.38 ATL build tools. I have the following issues:

  1. When I create a C++ class and work on it, I close the editor and then restart it. The C++ class does not appear in the Content Browser. When I run Live Coding, the C++ class appears in the Content Browser.

  2. I cannot open a blueprint class derived from a C++ class.

  3. When I open a UE project in Visual Studio, it asks me to install the previous version of MSVC and the C++ ATL build tools.

After installing them according to the instructions in step 3, all my issues were resolved.

However, I cannot create an MFC project in Visual Studio.
