Pages freezing

Ensure that Pages v13.2 is installed on Sonoma. I cannot reproduce your issue here with the first sentence satisfied.

Press and hold the shift key while launching Pages. You should only need to do this once after it freezes or crashes.

Hi leograchov,

This article has some steps that may help if Pages isn't working as expected: If an app on your Mac stops responding, closes unexpectedly, or won’t open

If the issue continues, try testing in safe mode. This will start up your Mac so that it performs certain checks and prevents some software from automatically loading or opening, which could help narrow down the cause of the issue. This article will walk you through the steps: Use safe mode on your Mac

If you're using a Mac with Apple silicon

1. Shut down your Mac.

2. Press and hold the power button on your Mac. As you continue to hold the power button, your Mac turns on and loads startup options. When you see Options, release the power button.

3. Select your startup disk. It's named Macintosh HD, unless you changed its name.

4. Press and hold the Shift key, then click the “Continue in Safe Mode” button below your startup disk.

5. Log in to your Mac. You might be asked to log in again.

If you're using an Intel-based Mac

If you're not using a Mac with Apple silicon, you're using an Intel-based Mac.

1. Turn on or restart your Mac, then immediately press and hold the Shift key as your Mac starts up.

2. Release the key when you see the login window, then log in to your Mac. 

3. You might be asked to log in again. On either the first or second login window, you should see ”Safe Boot” in the upper-right corner of the window. If you can't start up in safe mode, make sure that your Mac isn't using a firmware password.

Regards.
