I am trying to package my project and I get this error:

If part of a plugin, also check if its ‘Type’ is correct.

I know it could be many things, and that this is a very common error, but none of the solutions I have tried have worked for me. I have installed Visual Studio, .NET, and updated the SDK. I need help, I have been working on this project for more than two years and this is the 4th time I am going to Build.

Hey @herox69! Welcome to the forums!

This is most likely the root of your problem. I would check with this plugin to see if there is a recurring issue with others on their marketplace page and check their discord!

It was definitely that. Thanks for your quick response!
