Getting a 'Can't open Serial Port' error at upload.
When will OTA be supported?
The "Access is denied" error can be caused by another application having the port (COM14 in this case) open. That could even include another Arduino IDE window with Serial Monitor open. It also might occur if you click the upload button again while the previous upload attempt is still ongoing.
You should also verify that COM14 is actually the port of your Feather and not some other device attached to your computer. You'll know this if the port appears/disappears when the feather is connected/disconnected.
If you can't find the cause of the port conflict, try restarting your computer. On rare occasions, a glitch can cause the port to get stuck open and restarting the computer will fix that.

I think the lack of network upload support in Arduino IDE 2.x is tracked here:
Be sure to check the linked Arduino CLI issue to get all the information on the subject.
