You need to rebuild the plugins, for example - command prompt:
<UnrealEngine install path>\Engine\Build\BatchFiles\RunUAT.bat BuildPlugin -plugin="<path to the plugin>\AdvancedSession\AdvancedSession.uplugin" -package="C:\Users\USERNAME\Desktop\test"
The -package is the output folder, you’d need to make a folder titled ‘test’ for the above to work.
