ShadowTrackerExtra

https://support.apple.com/en-us/HT207165Ask the app vendor if they use that ShadowTrackerExtra app as part of their package.

If restarting the iPhone does not address your issues reloading a deleted app, then back up the contents of your iPhone to iCloud or to a local Mac or Windows system, then factory reset the iPhone, and then restore the iPhone contents and re-download the apps as necessary.

Here's what Apple recommends here: If you can’t download or update apps on your iPhone or iPad - Apple Support

...but that article doesn't cover that can't-delete app, which appears to be a corruption, and corruptions usually mean a reset-and-reload will be needed. This and checking directly with the vendor to see whether that other app is related.

By all appearances, that app appears to be part of PUBG.

Check with the vendor to confirm that.

According to the Apple iOS app store listing for the PUBG Mobile Runic Power game, the support email is pubgmobile_cs@tencentgames.com

How can I do with this link sir❤️

I posted the support email address, and will assume that you do not need an explanation of how to compose and send a message asking your question. Ask the app vendor if this is expected.

Ah, so you do know how to use mail!

¡Excelente!

Use your writing and mailing skills, and pose your questions to the game app maintainers, and await their answer.

I’m not a customer of Tencent games, and not familiar with this game, not am I familiar with the details of nor the status of your particular iPhone. You are. You will want to send the request yourself.
