Source code project doesn't build after adding new plugin

i wanted to install a new plugin to a sorce code engine, so first i installed it to a 4.25 engine then copied the plugin to the source engine, i opened the project and enabled the plugin then i had to restart for the plugin to take effect, but then i tried to open the project it told me “failed to lunch editor” so i tried to generate visual studio project files, and it still didnt work, so i tried to rebuild the PROJECT and not the ENGINE but it showed me this error:

Help Would Be appreciated Alot!!
