Sending UDP Packages from installed .apk to pc in the same network

Hello everyone,
I am trying to send UDP packages from my Meta Quest 2 to my PC over the WiFi to which both of the devices are connected.

I have tried every solution I could, starting from adding the two lines in the Android Manifest about Internet Permission to disabling pc firewall.

My current architecture is pretty simple: I got a UDPSender script that sends a simple package to the IP address of my pc to the port 5000, and this script is running inside an apk installed on the quest; i then have a UDPReceiver that listens for received packages at the port 5000. Everything done using Unity (so, C# for scripting).

Using the Android Logcat of Unity linked to the Meta Quest I could see that everytime I try to send data, I get the error "Access Denied" with no more info. The Receiver on my PC, that in the meantime was running, didn't get anything and didn't throw any error.

I am driving crazy about trying to understand what I am doing wrong, if someone was able to solve a similar issue or managed to send udp packages from a Quest to an other device, please let me know!
