To anyone using Catalina, please check my previous message.
Use "Music" App on your Mac.
Thanks, I had the same error, similar experience here, on macOS catalina.
I opened the music ap, it said missing library, I clicked 'create new' , and closed the music app.
Then I was able to access the iphone contents in finder app.

Good to see this is still helping people - would have thought Apple would have fixed it with an update by now!

This is brilliant, thank you! Due to Covid (it's in another location), I cannot plug in the external hard drive on which I keep my iTunes library. Any suggestions how to trick my computer into letting me back up my iPhone without getting that message?

Create a new library on your local drive. Now you can connect and backup your phone etc as normal.
When you have access to your external drive again, redirect Music to connect to your original library. You will continue to be able to connect your iPhone to Finder as normal.

I am not computer literate at all and don't understand what the solution is, sorry. I try to connect my ipod nano 7th gen to my Macbook Pro and I get the message "couldn't communicate with helper application." This happened after the update to Catalina 10.15.5. I did go to Music>File>Library>Organize Library but Reorganize files is grayed out. I know my cable is good because my iPhone XR connects perfectly. I have tried resetting the ipod nano, didn't help. Does anyone have any ideas? Don't have an external drive.

SOLVED!!

2 hours with Apple Support didn't solve it - instead ended up resolving thanks to trial and error!

I have my iTunes media folder on an external TB3 drive - connected the drive and opened Music too ensure it was seeing everything OK.
Went back to Finder and everything now working fine and my iPhone shows up correctly (even if I now disconnect my iTunes external drive).
Maybe it just needed access to a file from my iTunes folder to get going!
It worked for me - Catalina

Just wanted to add: I had the same problem. Media folders on an external drive and "Could not connect to helper application"

I resolved it essentially the same way, but, added wrinkle: I had to create new empty folders for *both* 'Music' and for 'TV' before the iPhone would appear.

Once I launched both applications with new libraries I could see the phone again.

For me I had to make a new Music folder with the Music app and a new TV folder with the TV app. Only when I had done both did it work.

Well i tried all the things you guys wrote here but still can not open my iphone on my main user account. When i ve created other user there was no problem to open iphone. But this is no solution to change account to manage your phone:( Have you got any other hints what to do? This is strange, i can not open any of my iphones on main account even the haven't been conected previously.

I too signed up to this forum just to add my thanks!!
At first i wasn't sure what you meant about being able to see and play music, i could see the files on the USB using finder. Then i suddenly clicked you mean using the Music APP!!!
I opened Music and low and behold, is said it couldn't find my library! I tried to select the library file on the USB Drive - The App Didn't like it and wouldn't open it.
So i ended up creating a new library file on the USB. As soon as i'd done that, Finder could see my iPhone again!

Thank you so so much for your help!

I just had to sign up too. Thanks everyone for the help. After I set up the Music, TV, and Podcasts apps to work with their libraries, then My iphone showed up. Praise the Lord.

Wow, a year and a half later, google helped me find your solution. Thanks for asking about it way back then haha, solved my non updating too. Just opening my old iTunes media folder did the trick (even though I'm on catalina with no more itunes!)

Thanks
