[UE4-27] Visual Studio 22 to 19 error

[UE 4.27]

I was working on a project. I had to save the log via vitual studio, so I found some codes to export data from UE to visual studio.

After I had some error so I erased the codes in the explorer.

Some one said that using 2019 VS can be helpful so I downgraded the VS from 22 to 19.

And the problem happend.
I think making UE to VS 19 was problemetic

Mainly the error is about declaration

How can I solve it?
