App Store app keeps crashing

Hey there ManUtd13,

While we're unsure of the exact issue occurring when you try opening the App Store, we did find the next steps to take above your post If you can't connect to the App Store, iTunes Store, or other Apple services. If the issue is related to a connection error, these specific steps could be helpful:

"Make sure that your device is connected to the internet

Use any web browser to connect to any website. If nothing loads, use another device on the same network to see if it can connect to any website. If no other devices can access the internet, turn off your Wi-Fi router, then turn it on again to reset it. If you still can’t connect to your Wi-Fi network, contact your internet provider for more help. If only your first device can’t connect to the internet, get help with Wi-Fi on your iPhone or iPad, Apple Watch, Apple TV, or Mac.

If you use cellular service to connect to the internet on your iPhone or iPad, make sure that you have cellular data turned on for the app that you're using. To do this, open the Settings app, tap Cellular, then turn on Cellular Data.

Update your software

Update to the latest version of iOS or iPadOS, macOS, tvOS, watchOS, or software for your non-Apple device. Then try to connect again."

If you do update using the steps above, be sure to back up as well.

Cheers!
