Assertion Failed when closing and reopening game

Hello everyone, couldn’t find anywhere the same error so I figured I should post this.
I am currently trying to package my project (Still as Development, not Ship) to share with my colleagues a demo but I keep getting an error and I can’t figure out what’s causing it.
Currently on 25.4 and developing for Windows
If I restart my pc and re-package the game the error gets fixed but the target directory it shows doesn’t exist in my PC.
It’s not the first game I develop but it’s the first time I see this error, if anyone can help I would be really glad.
If you have any questions I’ll answer with anything that can be helpful
