I have two Realtek based USB WiFi dongles for my desktop, one quite old and slow but worked without needing additional drivers installed, and one newer (TP-Link TL-WN722N) that needed an 8188EU driver installed from AUR.
I found three drivers there. I couldn't get the first to work (https://aur.archlinux.org/packages/8188eu-dkms), but the second one did (https://aur.archlinux.org/packages/8188eu-dkms-git) and for a few days I was happily using both of my WiFis at once (because why not). FWIW I use git clone to fetch and makepkg -si to build.
But then at some point I rebooted my system, not for the first time since installing the driver either, but this time it wouldn't get past the disk checks to a login. I figured out that by unplugging the TP-Link and rebooting again allowed the system to boot normal.
Then with the desktop up and running and the old WiFi working, I try plugging in the TP-Link and it doesn't work. But what is even weirder, my load avg starts going up, and I see using top that systemd-udevd is going out of control, climbing up and up, even after I unplug the dongle. The system eventually becomes unresponsive, so I press the reset switch and boot again.
I'm using systemd-networkd and iwd. I tried looking at some journalctl for the time it wouldn't boot and didn't see much -
[23:09 0.03|brian@erdos ~] journalctl -p 3 -xb -2

Feb 26 22:50:05 erdos systemd-udevd[230]: wlan1: Worker [1032] processing SEQNUM=3645 killedwhere wlan0 has been the older WiFi and wlan1 the newer one, per looking at iwctl device list.
I found no info for the next session (-xb -1) on the systemd-udevd runaway.
I've also since then had some issues with the older one not functioning on boot, but if I unplug it and plug it back in it gets picked up and starts working.
I did sudo pacman -R 8188eu-dkms-git and the issue with systemd-udevd running away when I plug in the newer dongle doesn't happen anymore. I also tried the third driver (https://aur.archlinux.org/packages/8188 … -dkms-git/) but the results were similar.
I'm not sure where to go next to diagnose what happened to my once-functioning driver (I can only guess that either a pacman -Syu or something else I messed with broke it). I currently have uninstalled the drivers to keep my system going, but I could reinstall and try things to troubleshoot.

Narrowing down the problem statement, having thought and experimented more.
- Functioning Arch system, but I want to use my newer USB WiFi dongle instead of this old slow one.
- I git clone https://aur.archlinux.org/8188eu-dkms-git.git, and do makepkg -si
- Everything is still fine at this point. If I reboot, whatever, everything is ok.
- I plug in my newer USB dongle. Immediately I can see systemd-udevd eating more and more CPU, load average goes higher and higher, system becomes unusable. Unplugging it doesn't help at this point, udevd keeps climbing.
- Press reset switch and unplug that newer WiFi, everything is okay
BUT, this WiFi dongle was working with this driver a few days ago, something has changed. If I remove the driver and/or not plug in the dongle, my system is fine again (except I want to use this newer antenna, the old one is about 1/3rd the speed).

I rebuilt the 8188-dkms-git driver, ran journalctl -f in one terminal and watched top in another, and when I plugged in the TP-Link I saw the load start climbing and systemd-udevd pegging the CPU. After a few minutes I got this in the log:

I tried running strace on the PID of systemd-udevd and recorded what happened when I plug in the TP-Link. Comparing this with the same for the other working WiFi dongle, I found the part where it goes off the rails.

...And those last few lines keep repeating.

I decided to go buy an Intel AX200 based PCIe WiFi card, plugged it in, booted, and it worked immediately, no configuration required. Sometimes the simpler solution is to get hardware already supported by the kernel.

For what it may be worth, there is a driver in the Kernel tree already, and that module from AUR is not strictly needed. I can use the same TL-WN722N dongle with a fresh installation.
However, I wish I had bought the Atheros-based version instead, for which the "ath9k_htc" kernel driver might be more mature. I fully agree that buying something with known support is a good idea.
