RTL8723DE Network Adapter Doesn't Work on Linux 5.9.1-1

Hello,
I just tried the new Kernel Updates that were pushed to the stable branch, and decided to try the new Linux 5.9.1-1 kernel. Upon doing so, my network adapter refused to show any nearby WiFi networks. I am now running the Linux 5.8.16-2 kernel after trying the other one and I am able to connect to my WiFi just fine. There is no problem that is hindering the usability of my computer, just that the latest Linux kernel breaks my WiFi compatibility. I am posting this hoping that this will go to the right people and that this will be fixed in a later version of the Linux 5.9 Kernel.

Please post the output of inxi -Nazy and lspci -k for both kernels.

Just stay on 5.8 for the moment or do you have a specific reason to change to 5.9? Enjoy that Manjaro offers you to select a kernel easily and to choose which fits best to your hardware. 5.8 will be updated for a long time, so no hurry to change to 5.9 now.

No specific reason to switch to 5.9 other than just to see if it improves performance of my computer at all. I just like to try the newest updates out to see how they run on my machine, knowing I have the ability to roll back if needed.

Something bizarre happened during the switch back to 5.9. For some reason, now my WiFi adapter is working fine on this new version. Maybe a bug occurred during the 1st session when I made the OP. Anyways, I will still provide you with the outputs of those commands.
