Failed to build....Error relating to skeletal mesh or whatever but all looks fine....

Hello again!

Thanks for testing, we can rule out settings migration conflicts. Yet the issue seems locked into a faulty element inside your game.

To ensure no other setting shenanigans are affecting us here, could you setup a build on a fresh project? Just minimal elements, could use tutorial or sample assets. The idea is to ensure that the build problem does not trigger on other projects.
