based on what I see it's trying to give you a nil value when it's not allowed to, I haven't seen xen for awhile so idk about any fixes, could try fixing it yourself with ai or ask someone who knows lua

If anyone has info on this please help bought the paid version of it had it for 4 years suddenly this error started appearing until now.

It even says content pack in the description literally saying you gotta get it here- https://www.gmodstore.com/market/view/xenin-f4-the-darkrp-f4-menu

to litteral everyone pasting in your errors this is not a free menu this is on gmodstore com you did not buy it therefor you do not have the required lua files
