I understand the problem. It cannot export openMenu from the qb-menu file, but I do not know how to fix it.
I’m suspecting it could be that the exports system is dynamic, but I’m not too aware of how the system works in the backend.
Can you try changing line 5 to:
exports["qb-menu"]:openMenu({
Let me know if that helps!
I’m having same issue but your solution didn’t work for me
