4.20Load failure after packaging #12

The serial port cannot be read after the project is opened

There were some people in the forums with a similar problem. I've had that too some times. Try setting the plugin to not installed:

open its uplugin file;
change "Installed":"true" to "Installed":"false".

If that doesn't do it, also try adding a Serial variable to any Blueprint that's not a Component Blueprint. That solved it for me once. It was as if Unreal wouldn't consider Serial as being used by the Component and wouldn't compile it with the project.

Also check if the Serial port hasn't changed on Windows.

@SnowflakeSmasher26 What did you try already? Are you trying to use it on a Blueprint only project? If so, you need the binary files. Just the source code won't do it. You can get the binaries in the releases. The latest release has binaries for 4.24.
