Build failing with unknown error, I'm getting desperate!

I have tried to build my game after doing a small update and the packaging is failing with an unknown error. Since my last successful package I have been using the Nvidia Omniverse live link plugin so I’m thinking this is at fault. I have tried removing the plugins from both the Unreal Engine plugins folder and the projects plugin folder to no avail.

I am getting desperate at this point as I need to get a bug fix out (the game is already released in early access)

Output log is below

If anyone could help I would be really grateful, I have not had a lot of luck developing this game (including the fact that no-one is buying it) and am seriously thinking of jacking it all in at this point…

The first thing that sticks out to me are all the spaces and dashes in the path to your project. D:\Game\Recordance_B 5.0 - 2 5.1 5.2 Unreal Engine and all the underlying systems work best without those extra spaces and symbols Try renaming that project folder to “Recordance_B”

Hi Stephen.

The game has packaged successfully multiple times before using the same naming scheme. It has only been recently since I was playing around with Omniverse and live link etc that it has failed to package

I’ve just disabled all plugins relating to live link and it seems to be packaging properly now ( I hope) so fingers crossed…
