Packaging on Windows and Linux. Bug

Me and a developer are developing a game but are running into issues. I can package and build on my Linux desktop using Ubuntu. He is attempting to package the game on Windows but running into errors below. I’m not sure of the problem and he isn’t. Technically there shouldn’t be a issue.

I’m attempting to load the project onto a laptop running Windows 10.

Do anyone have a idea what might be the problem?
