I don’t know where you are, but this isn’t always enough. If it’s your employer’s IP it’s not yours to license to begin with.
In my situation, it even extends to any hobby projects I work on and I don’t think my situation is unusual.
That said, most employers don’t care about hobby projects with no earning potential.
I had this issue and it only worked when I downloaded it from the website and ran it, not from steam or flatpak. I don’t have it installed anymore and I’m not sure what the underlying issue was, but you can try that.
