Update my app

Check the App Store and iTunes Store to see if there are any updates for apps/purchases. A request for another Apple ID password is often caused by updates to apps/purchases that were made when using the other ID. Those purchases are tied to the other ID and can't be transferred. One option is to delete the apps/purchases made by the other ID and download them using the new ID if desired. If necessary, check your purchases history to see which apps/purchases weren’t made by the current ID.

Refer to the Following:

A. Disable Cellular:

It will not update with cellular enabled. So, if Cellular is enabled, disable it, then proceed with the update.

B. Update an iPhone:

Update your iPhone using:

• the iPhone itself
• a Mac, or
• a PC, even.

How to do so....

Two Major Steps: - Backup then Update

1. Backup First: Make a backup of your device using iCloud or your computer

2. Then, Update Using these Links:

• On the iPhone itself: Update your iPhone, iPad, or iPod touch - Apple Support
• From a Mac: Update software on iOS devices in iTunes on Mac - Apple Support
• From a PC: Update software on iOS and iPadOS devices in iTunes on PC - Apple Support

Some other things you can try. Do you have access to another WiFi network where you can try? That has worked for several people.

Try a restart.

Restart your iPhone, iPad, or iPod touch         

Try a forced restart.

Reset Device.      

If necessary

Hard reset.        

Do a backup and try a factory reset. Then restore from your backup.

Restore to Factory setting.      

Backup - Restore your device from an iCloud or iTunes backup.

No worries - yes I read it - If you are connected to Cellular (making the assumption based on your screenshot), then disable it. See if you can successfully update through Wi-Fi.
