Hi HanMay,

We recommend that you try restarting your Apple Watch since apps are not opening when you launch them.

Restart your Apple Watch - Apple Support

To perform the recommended troubleshooting steps via the link above, complete the steps in the section titled "How to restart your Apple Watch if you have watchOS 9."

1. If your Apple Watch is charging, take it off the charger.

2. Press and hold the side button until you see the power button  in the upper-right corner of the display.

3. Tap the power button.

4. Drag the Power Off slider.

5. After your watch turns off, press and hold the side button again until you see the Apple logo.

We recommend the steps above because they will show you how to restart your Apple Watch when apps are not working as expected.

If you’re still experiencing the same issue, try uninstalling and reinstalling the apps not working on your Apple Watch.

Delete apps from your Apple Watch - Apple Support

1. Press the Digital Crown to see all your apps on the Home Screen.

2. Touch and hold the display until the View Options screen appears.

3. Tap Edit Apps.

4. Tap the delete button  on the app that you want to remove, then tap Delete App to confirm. Not all built-in apps can be removed. Apps that you can't delete don't show the delete button.

5. Press the Digital Crown to finish.

If you remove an app from your iPhone, that app is also deleted from your Apple Watch. If you want to restore an app, including built-in Apple apps, you can download it from the App Store on your iPhone or Apple Watch.

Download apps on your Apple Watch - Apple Support

1. Press the Digital Crown to see the Home screen, then tap the App Store.

2. Tap Search to find apps using Scribble or Dictation or scroll down to discover featured apps and curated app collections.

3. Tap an app to see its description, ratings and reviews, screenshots, release notes, and more.

4. Tap the price or tap Get.

5. When prompted, double-click the side button under the Digital Crown to download and install the app.

In the App Store, if an app has a Get button instead of a price, the app is free. You won't be charged for downloading a free app. Some free apps offer in-app purchases and subscriptions that you can buy. Subscriptions and in-app purchases give you access to more features, content, and more. Learn more about in-app purchases and subscriptions.

Please let us know the outcome after giving the above steps a try.

Thanks for using the Apple Support Communities.

Cheers!
