iTunes stuck on "Syncing iPhone (Step 3 of 5) Preparing to Sync" when trying to sync iPhone to new Win 11 laptop

iTunes Version 12.13.1.3, iPhone 12 128GB iOS 17.2, directly connected to laptop via Apple Lightning to usb-c cable, Win 11 ver 23H2 (OS Build 22631.2861), 32 GB RAM.


Since getting my new laptop, I have tried to sync iPhone via iTunes. Whenever it's a backup or a sync running, iTunes will get stuck at "Syncing iPhone (Step 3 of 5) Preparing to Sync". Under iTunes in Taskmgr, I can see 4 Console Windows Host, distnoted(32 bit), iTunes, MDCrashReportTool (32 bit), MobileDeviceHelper (32 bit), MobileDeviceProcess, Runtime Broker, and SyncServer.exe (32 bit). I've run through the diagnostics in iTunes, and the only issue it finds is "iPod support service is not installed". None of the troubleshooters seem to resolve that. And iTunes will sit on "Stuck on Syncing iPhone (Step 3 of 5) Preparing to Sync" indefinitely, if allowed. And yes, the computer is trusted, and I'm logged into the iTunes store.


I've seen on the internet where doing an "endtask" on MDCrashReportTool will move the sync process to completion, but nothing ever syncs. It essentially ends the process.


Short of wiping my phone and starting all over, is there any other recommendations to get by the "Stuck on Syncing iPhone (Step 3 of 5) Preparing to Sync" phase?

I solved my problem. I had an Apple Watch paired to my iPhone. I had gotten rid of the watch, but never unpaired it. After unpairing the watch everything syncs okay now. Lesson, if you get rid of the watch not only remove it from your devices you also need to unpair it from your phone!!! Life is back to normal.

I was hoping and EXPECTING with all the users with this issue the "stuck on preparing to sync" would be fixed in 17.3. It is not. Both disappointing and showing a lack of responisibility for their customers.


Now, in the process of trying to fix this i have made it worse.


My phonwe and outlook always synced esily and as expected. Trying to fix this I ** two things: Unchecked sync contacts and tried reset sync. Both several times. When I rechecked sync contacts I get several possible erros. Tonight's : this will change more than 25% of you contacts on this phone. Add 22, delete 191 and something else for 6. I cancelled that.


Is it possible to get back into sync? I am reluctant to try one toime replace contacts on computer from this phone. Can I trust that?


Appreciate any insight. There are several similar threads on this hear so forgive me for posting more than one, but woul dlike visibility to fix this problem.


Thanks.
