I went back and read the entire topic again. There appear to be some discrepancies which re-frame how one views this situation. I will make some observations and ask questions that should help us get steered in the correct direction for this issue.

If you can see your laptop's screen while the lid is shut, please let us know how you do that.
Are you putting the computer to sleep by closing the lid or are you using a different method? Many computers will automatically wake when you open the lid. It appears you have your computer go to a locked state when sleeping so when you wake the computer by opening the lid you find your locked screensaver requesting your password to unlock the computer. That is quite normal.
There are a number of people with laptops which immediately resume from sleep a second after they are put to sleep. That is a different issue and at this time I do not know if that applies in your situation. Usually, we recommend trying a newer kernel in those situations, but you would have to move to LM21 to try that solution.

The network icon in that image indicates your system is not connected to the network when you see that message.
A couple of posts later you clicked the details button which indicated org.freedesktop.login1.suspend-ignore-inhibit was the issue. I did some searches on that and apparently there are computers which have been known to disable the network connection
when the computer goes to sleep. That would match your network icon indicating disconnection.
That would also mean the screen you are seeing is a confusing message because you already woke the computer by unlocking the system. This sort of seems to be a chicken-and-egg type of situation. You already woke the computer from suspend so the message telling you that you have to authenticate is a left-over message still in the queue.
I have already mentioned there may be issues with your computer's networking situation. This is likely a firmware or driver-related situation if it is not hardware related. The networking hardware is not responding properly. I have no clue how that would relate to transferring large files unless you are transferring those files from the cloud/internet to the usb drive. Is that what you are doing?
However, after you re-installed Linux Mint, you indicated the following:

which sounds like your computer went to sleep when you closed the lid?

Are you using the Menu > Shutdown option to shut down?
If you are using the power button then it is possible your laptop is set up to put the computer to sleep when the power button is pressed. A number of laptops have different actions for a short-press and a long-press of the power button. That could explain why you are seeing the screen-lock.
Or this could be another issue with the network device. We already know from the information I found previously that others have had issues with it.

We already did. You pressed the details button and it told us which application was stopping the process.
MathMachine4 wrote: ⤴Fri Mar 24, 2023 10:29 pmAlso, is there any way to know why the failure to properly restart is consistently associated with a failure to suspend? Because I never see a message saying "an application is preventing you from shutting down", it just flat out restarts the computer.
I don't understand what you man by a failure to properly restart. There are two different ways to restart the computer. One is a shut down which completely powers down everything. That requires re-powering the hardware to start again.
The other way is to reboot the operating system which does not involve powering down the hardware. That way only restarts the operating system and that is what sounds like is happening in your case.
