RTL8814AU driver Not Working After Linux Kernel 6.3.1 Zen Upgrade

Hello everyone,
I am seeking your kind assistance with a problem I am facing after upgrading my Linux kernel to version 6.3.1 Zen. My wireless network adapter, a TP-LINK TL-WDN7200H (an external USB wireless adapter), which uses the RTL8814AU driver, stopped working properly after the upgrade.
The symptoms I am experiencing are as follows:
1. The LED indicator on the adapter does not light up.
2. The adapter does not automatically connect to Wi-Fi.
3. When I try to manually connect to Wi-Fi using NetworkManager, it gets stuck at "Setting the network address", but the network is accessible during this time. However, after a short time, the connection fails and I get an "IP address unavailable" message.
I have tried several solutions to fix this problem, including installing the blackarch/rtl8814au-aircrack-dkms package, the rtl8814au-dkms-git package from AUR, and the latest version of the driver from https://github.com/morrownr/8814au. Unfortunately, I ran into errors installing the first two packages. I posted the error messages on Pastebin:
- For blackarch/rtl8814au-aircrack-dkms: https://pastebin.com/SZWqE8AN
- For rtl8814au-dkms-git from AUR: https://pastebin.com/h52FcPAV
The latest version from the GitHub repository did not produce any errors during installation, and the network was initially accessible after a reboot. However, NetworkManager still displayed "Setting network address" and the connection finally failed after some time, just like before.
I would appreciate any help, advice or suggestions on how to solve this problem. I have provided as much information as I can, but please let me know if there is any additional information that would be helpful in troubleshooting. Thanks in advance for your time and help.

AFAIK there should have been upstreamed improvements for these kind of adapters. Have you tried dropping these third party packages altogether? If that didn't help you'll have to wait for upstream to add compatibility for the new kernel. Maybe opt for using/having the LTS kernel around for these kind of compatibility concerns.
