When I connect my iPhone or iPad to my MacBook Pro with a cable, Finder shows me this message:
An unknown error occurred (7004)
And there's nothing else I can do.
I have restarted all devices, removed antivirus and firewall, and there's no way around it.
I have a:
Anyone has an idea?

Well a way to fix this issue is by going to your home folder and deleting the music and Apple TV libraries. After that, reopen Apple TV and music and the apps will recreate the libraries. So then the error should go away.
Also here are the paths
Music: Your Username\Music\Music\Music Library
Apple TV: Your Username\Movies\TV\ TV Library

That error is not in the list. Most of them are related to USB failure or storage on iPhone totally rammed full. Check those.
You were unwise to install any 3rd party antivirus or firewalls on any of your devices and it is possible that it, or they, did not get removed completely by the uninstaller.
You could get etrecheck from etresoft.com for the Mac and run it with full disk access.
Attach the report using the Additional Text icon on the Mac browser.
Some people on here may spot something or you can create a new post on the Big Sur forum.
I would post in the Big Sur forum. Seems to be common to that MacOS
I have this problem also. Just updated to Big Sur 11.2.2 and when I click on my iPad in Finder, it gives this 7004 error. I have tried to restart both my Macbook Air (M1) and my iPad Air 3 to no avail. I don't have any antivirus software installed. My iPad still has over 30GB of free space.
EDIT: Sidecar works via Lightning cable so it's not a connection problem per se.
The firewall is macOS' own firewall, and the antivirus is Avira's, I believe quite a notorious brand and I'v been using it for about ten years without any problem of this kind. I used wrongly the word "remove", I didn't remove them, I just deactivated them.
I will probably give a try at what you suggest. Thanks.

Ok thanks for that. I would strongly advise against re-installing Avira unless you are contractually obliged by an employer. Keep us in touch as 7004 is new to me.
same issue with air m1 and iPhone 8 Plus and iPad 6th gen
Been getting the same 7004 error on my M1 Mini, with OS11.2.3, and 6S iPhone (14.4.1). Tried multiple USB cords, restarts. No solution yet.
having the same issue, anyone found the solution yet ?
I'm on m1 with latest update. Though imazing is working.
I had this thread moved to Big Sur forum as it seems to be the common denominator.
MBP Big Sur says unknown error 7005 when iPhone or iPad are connected This is an earlier posting dating December 2020 regarding the error 7004 - if useful good if not disregard.
These things have a habit of being fixed eventually
Although error 4000 in itunes for Windows is still there after months.
An unknown error occurred (7004)
