I have problems with online features.

Hello, first it's a pleasure to be able to help you today.

My name is welcome to the community and Merry Christmas.

Hello Alessio, when it says it can't run "online function in any game", what exactly is it trying to do, would it be playing online, what game would it not be able to run what it wants?

Do you have an active Game Pass Ultimate or Live Gold subscription?

If you can give more details.

if this helps in any way heres a screenshot

I noticed you mentioned Wi-Fi in the original post...have you tried using a wired connection? If you can't use a wired connection for whatever reason, maybe try to use your phone as a Wi-Fi hotspot to workaround the PC Wi-Fi and see if that does anything (assuming you have the data capacity of course)

Also, is this the only game you encounter online play errors?

If I was speculating, I'd think the issue is with your router or your internet connection (maybe your ISP has certain protocols or whatever interfering) but can't say for sure.

I did find a thread from a cuple of years ago which may be of help...I glanced through the first page and there are a couple of possible solutions to try:
