Occasionally I have to do a requisite reboot after a Ubuntu OS upgrade. I dread it.
Every time it involves losing my IDE ports.
If you look at my screenshot of the IDE at the bottom right of the screen it shows the
ACM0 port assignment as if everything was in working order.
I hope I have overlooked something one of you astute users can point out.
I don't know much about Arduino in combination with Linux. However, the right bottom only indicates the last used port, not the active port or the existence of the port.
brltty might be a suspect; uninstall it. lsusb can tell you if the board is detected; not sure if it shows the VID and the PID, else they will be in dmesg dmesg might give you additional information.
Instead of running usermod immediately, first check if you are still a member of dialout; you will never figure out if it's the cause of your problems or not in the way you do it.
I removed brltty. Closed the IDE and reopened but no effect regrettfully.
I do know before this OS update and reboot that whether I had an ESP32 or UNO WiFi Rev2
hooked to the ports my OS/IDE immediately "saw" whenever I unhooked a USB cable and
immediately show the port again upon reconnection.
If I can ever get my finger precisely on what happens to the IDE after these OS updates I will
be able to quit pulling out what little grey hair I have left. I really really do not want to do yet
another IDE install as a workaround. I need to know what is causing this so I can immediately address it going forward.

I remember now when booting up this morning that I did get some USB 5-2 error messages after the POST and the system was generating the "journal" status, for lack of a better description. It is at 11:11 am that I plugged the USB cable to the UNO WiFi back in.
Man oh man. I booted up the Grub Menu and then the arrow keys would not work. I had
to go digging around in my computer graveyards to find an old plug in style keyboard.
I did revert from kernel 5.15.0-52-generic to 5.15.0.48-generic.
NO CHANGE.
I need to figure out what is causing those boot error messages about usb 5-2.
"usb 5-2 device descriptor read/64, error -110 "
"usb 5-2 device not accepting address"
All of this happened after an OS update and reboot. ....sheeesh....
"And the module can also not be unloaded when running 5.15.0.48?"
Probably. knowing my luck.
After reading this link, albeit dated, I am not sure about easily restraining that uhci_hcd module. I get over my head quick playing around with consequential files. May not have any choice but to reinstall IDE for the umpteenth time.
For anyone interested and might see something worth noting, from dmsg

Sounds like you have a USB hardware problem. Try powering off your computer off and on versus restarting. Sometimes power off/on can reset internal hardware that cannot be done by restarting.
If the problem persists, try different USB ports on your computer. Perhaps one or more ports is flaky. If using a docking station, undock and plug directly into the computer USB ports. If using a USB hub try without the hub. If not using a USB hub, try with a powered USB. Some USB 3.x ports do not work with with old USB 1.1 devices such as used on Arduino boards. A USB 2.0 hub might
help.
Try different USB cables. If the cable wiggles around when plugged in, the USB connector may be damaged. If using USB Type C ports (very new computers have USB Type C ports), try different adapters.
In summary, methodically check/swap everything between the board and the computer USB port such as cables, adapters, hubs, docks, etc.

One thing I have noticed is that USB errors on power-on startup completely go away if the only thing I leave attached is the mini plug for the mouse. I have an old style keyboard PS2 plug
I am using right now instead of a usb corded keyboard.
the errors are similar to:
"usb 4-2 device descriptor read/64, error -110"
They used to be usb 5-1 but now are usb 4-2. ???
If it was hardware related, and it still might be, it is strange that the issue arose right after a Ubuntu OS update and restart. And this has happened before with these updates and I ended up just reloading EVERYTHING. ughhhhh...
I an loathe to continue doing updates if this crap is always the result. I like keeping my software updated but not at the expense of losing port functionality.
