macOS 14.1.1 App Store Crashes immediately when opened

I think the problem is in the Discover page. Here's how I got around it.

1. Launch the App Store.
2. As soon as you see the window, press ⌘2 repeatedly to move to the Arcade page (doesn't matter if you've subscribed or not; just get off of the Discover page).
3. Stay off of the Discover page; it seems to be crashing the App Store app for now.

The same thing is happening to me on my M1 Max MBP running Sonoma 14.1.1. Today (11/23/23) is the first time I've had this happen. Tried rebooting but no change. App Store crashes as soon as its window opens.

Managed to get it up and running, it seems to have something to do with the Discover category. I clicked on every category and it works then I clicked on Discover and it crashes, something in that category is causing the crash.

See the following Apple articles:

You need to have a good Service and/or Wi-Fi.

If they are On, turn Off Hotspot & VPN.

Charge the battery > 70%.

Exactly the same for me. Not sure when I last accesses App Store but today when I tried to access it crashes on startup. Based on some previous posts I have tried the following:

• Restarting
• Starting in safe mode
• Adding a new user and trying from that account
• Trying safe mode in new account :)
• Re-installing Sonoma

None of these have fixed it.

I'm on 14.1.1 on a MacBook Pro M1Pro

Same here.  From the crash report it appears to be a bug

I tried these common troubleshooting methods to rectify the issue:

• Open Activity Monitor and Force Quit appstoreagent (no effect)
• Used mas command-line tool to sign-out and reset App Store (no effect)
• Restart in Safe Mode (no effect)

Short of re-installing macOS and all my applications, I am not sure how to proceed either.

Nothing to do with VPN or Wifi, tried it with my 2014 Mac mini with Monterey works fine same wifi connection.

I also have Parallels Desktop with Mojave on my 2018 Mac mini running Sonoma , App Store works fine in Parallel running Mojave. Crashes with Sonoma, don't know if it's working in Ventura. Not about to reinstall Sonoma.

Here to report the same issue. It happened in 14.1.1, M2 Macbook

Thank you - I can also confirm this works.

Looks like the macOS App Store's Discover webview contains a bug that is causing AppKit to crash as soon as the page receives a focus event.

I feel embarrassed for Apple.

This worked for me - thanks!

Running macOS 14.1.1 on MacBook Pro Intel i7

I re-read some of the replies, and tried pressing ⌘2 repeatedly, which stopped the crash. Then I went to update, and successfully updated an app

THANK YOU! I was going out of my mind trying to figure it out. Got my brand new Mini M2 up and running today and was never able to get in to the store - not even once without that error.

Hopefully, they will patch that pretty quickly.

Crash, crash, crash, and crash again.

This is new today, Nov 23.

A Black Friday gift?

This was very helpful. When launching the App Store on Mac, quickly click on another category (Arcade, Create, Work, Play, etc.) and it will stop crashing. The Discover category is causing the app to crash. This is a good work around until Apple fixes the bug.

The same thing is happening to me since upgrading to macOS Sonoma 14.1.1, I'd say the issue was created by the update. Tried to go to App Store to update my apps after install, I tried everything I know. I using MBPro M1 Max 10 core CPU 32 core GPU 16 core Neural Engine 32 GB Ram 2TB Drive
