ExitCode=6/Import class not available on the platform

I’ve got myself in a pickle I don’t really understand. The project is just Blueprints (minus the plugin).

So I have a game completely done. It utilizes a plugin not found on the marketplace called “Mazes”. It utilizes C++. This has not caused me any issues up until now, and apologies if what I ask is illogical.

If I type this, I get the “import class not available on the platform”, yet it ALMOST completes packaging:

If I delete it (TargetAllowList), I get ExitCode=6.

I did everything from generating the .sln file, swapping between those errors, deleting files. If I delete the Mazes plugin, it works, however, sadly, I need it for the game. So I’m pretty stuck especially because I don’t mess with C++ much and I have 0 errors with the game itself, JUST packaging. (VS is up to date, SDKs and all with the tool plugin)

If you can disable Live coding and try again.

Did that, still doesn’t work unfortunately
