WiFi disconnects automatically, automatically unchecks "Connect Automatically" box from connected network, cannot uncheck the box for other networks

I have been having this problem for over a year and a half, ever since I built this PC.
When connecting to WiFi, it often says "Can't connect to this network".
When connected, I do check the "Connect Automatically" box, but it keeps unchecking itself even though it's still connected. I check it again, and it keeps unchecking after a while.
The WiFi also randomly disconnects, and during that time, the box automatically becomes unchecked.
I also cannot uncheck that box from other networks I have never connected to.
I have tried to turn on and off my PC, resetting, reinstalling and updating my drivers. I have disabled every power-saving setting for the computer and the Wi-Fi adapter. My Roaming Aggressiveness is set to Medium-Low as well. I am running on 2.4 GHz, with an Intel AX210 WiFi 6E WiFi + BT 5.3 card.
I need to resolve this problem as soon as possible because I do not want to use the TP Link extension for my wifi connection (because the extension is connected to Ethernet to the PC).
Additionally, my WiFi never auto-connects on login nor when I disconnect my Ethernet.

please try
control panel > network and sharing

in this window on the left is
change adaptor settings

in this window
right click your WiFi connection
and on this menu click diagnose

let the diagnostics run which may require a restart.

if that doesn't work open the device manager
find your network adaptor WiFi connection
right click and uninstall the device

close the device manager and restart the system
Windows will reload the required driver files

now try the WiFi settings to see if they are working correctly.
best of luck Steve ..

please burn a bootable live Linux USB using Rufus
once the bootable USB stick drive has been created boot in to the live Linux desktop

this will not install anything to your computer and run completely from the bootable USB stick drive.

now test the WiFi connection in Linux
if the WiFi is working correctly then you may have to completely repair Windows
using a repair recovery install.

if there are still errors with the WiFi in the live Linux desktop then the WiFi card
within the system is most likely faulty.

Rufus can be downloaded from the Microsoft store

Ubuntu live Linux distro download
