The issue that I have happens quite often. Whenever I boot into my laptop, it is quite possible that I will not be able to connect to any Wi-Fi networks, nor see them.
sudo systemctl status NetworkManager produces the following:

What can I do to fix it? I’ve tried to follow this article: RTL8822BE Wi-Fi not showing - #3 by Lila-Kuh but it did not help at all.

I suggest you keep searching. These types of issues seem to occur frequently, with differing causes ranging from hardware incompatibility or misconfiguration, through to local environmental issues.

It’s unlikely that one random thread will immediately provide a workable solution. Good luck.

Use a wired connection, remove all packages build from custom scripts or otherwise foreign to Manjaro eco-system

sudo pacman -Rns $(pacman -Qqm)

Then do a full unconditional sync

sudo pacman-mirrors --continent && sudo pacman -Syu linux610

And if you say it happens more and more often…

Possible hardware failure - or network interface card not properly seatend - even in a laptop.
