What to Do:

Being a continuum of errors, then here is what to consider....

A. Boot Into Safe Mode:

[Hold Down: the shift key upon boot]. Keep holding it down until you reach the log in screen. Then, log in, wait 30 seconds, and then boot up normally. In Safe Mode, damaged system files (i.e. caches) are fixed, and replaced.

B. Try New Admin User:

On your Mac. try creating a new Administrator User, and see if you can configure it with the new user. If it then works, then it is likely something configured in your current user. Delete the user when all is fixed.

C. Reinstall the MacOS:

So, as a last resort, reinstall the macOS. You would backup your Mac, and then reinstall it. Nothing would be removed. It's just that items that have been moved or corrupted, would be placed back to where they should be or replaced, respectively. But, more on that later, if it comes to that. I look forward to hearing back from you. Keep us up to date.

Important - Always Back Up the Mac Prior:

Create a Time Machine backup of your Mac, so that you can have something to restore your Mac from, should anything go wrong with the reinstall. Use an external drive at least 1.5 times the size in storage capacity.

D. Time Machine Backup Restoration:

Restore the Mac from a Time Machine Backup that you created prior to all of this happening.

"Is not a single OS issue. I have the same from 10 years along a lot of Mac OS. Actually the issue is on Mac Pro 61, 2 x Mac Pro 3,1, MBP Retina 2015, MBP 2019 and Mac Book Air 2013. It seems the Apple don not take in big consideration USB devices. I have no experienced any problem with Fire Wire 400 and 800, some with Thunderbolt 2 (these are related to the USB external device connecting)."

Reset the SMC and your NVRAM:

On all of your devices giving you this issue (if not just this one), reset the SMC and the NVRAM. Sometimes when changes are made to the system(i.e. installations), system configurations (i.e. for ports) become manipulated, technically. So, reset the SMC and NVRAM. Try performing each thrice. It may take sometime, being certain you have the time to perform these resets.

It seems to me that you have two options. Option #1 is to continue to blame Apple (with no cause or reason) and wait for them to fix your problem, or (2), which is what most of us here would suggest. Download installed run the free app EtreCheck. Be sure to enable full disk access. The app will generate a report. Save it and post it below under "Additional text". That will give us a comprehensive view of what may be going on in your computer and we may find what is causing this problem. It is often some app which is in conflict with something else.

Got that Etrecheck report done yet? That report will answer hundreds of questions at once.
