Kali Linux 2020.2 Wifi Not Working (Realtek)

So: I’ve been working on trying to set up my WiFi on my new Kali linux OS. I am using a Realtek RTL8723DE 802.11b/g/n PCIe Adapter. iwconfig gives me the results:
lo no wireless extensions.

eth0 no wireless extensions.
I have tried installing a zip file from github but it is no longer there and when I follow the other instructions it wants a user name and password. I made an account but to no avail. (https://h30434.www3.hp.com/t5/Notebook-Wireless-and-Networking/Realtek-8723DE-wifi-module-amp-Bluetooth-Linux-driver/td-p/6477307) This is the link to that set of instructions.
I have also tried this (https://www.kalilinux.in/2020/03/how-to-install-wi-fi-driver-in-kali-linux.html) and it did nothing for me either.
Any help would be greatly appreciated, thank you.

rtk8192ee wifi firmare stops loading after ifenslave setup attempt (Debian 10)

I tried setting up Mode 0 NIC bonding using ifenslave between my Ethernet and WiFi cards on Debian 10.

After numerous ifconfig wls1 up/down, I was able to set up Bond0 until it stopped working. After undoing the setup, I realized ifconfig wls1 up wasn’t loading the WiFi adapter’s firmware anymore (rtk8192ee)

:~$ sudo dmesg | grep firmware

[5.201360] rtl8192ee: Using firmware rtlwifi/rtl8192eefw.bin

[5.201745] rtl8192ee 0000:24:00.0: firmware: failed to load rtlwifi/rtl8192eefw.bin (-2)

[5.201799] firmware_class: See https://wiki.debian.org/Firmware for information about missing firmware

[5.201845] rtl8192ee 0000:24:00.0: Direct firmware load for rtlwifi/rtl8192eefw.bin failed with error -2

I know I’m not missing the firmware because it was working before. Could this be a NetworkManager bug?

Please see my /etc/network/interfacesfile below

source /etc/network/interfaces.d/*

auto lo

iface lo inet loopback

Any ideas why the firmware is acting up?

Cannot connect to Wi-Fi network although my Realtek WiFi adapter is detected

I am facing a weird problem in Ubuntu 20.04 with kernel version 5.4.0-40. I have got a Wi-Fi adapter from Realtek for connecting my PC to the internet. From this answer, I have followed the instructions and downloaded and installed the driver from Github. It worked well for a few months, but since a few days I am facing the issue.

Ubuntu is detecting the presence of a Wi-Fi adapter, but whenever I am going to WiFi settings to connect to a network, the settings page says No WiFi adapter found:
enter image description here
I can understand that Ubuntu is detecting the adapter because WiFi option is appearing in the system tray when I connect the adapter:

I have also tried connecting to WiFi network from the command line with iwconfig. Here is the output of the command:

When I try to connect to a WiFi network with the iwconfig wlx00e0202c7613 essid <SSID> key <PASSWORD> command, I am getting this error:

What is the problem and how to fix this issue? I do not know much about networking in Linux, so please ask if more information is required.
