Apps won’t launch and appear as blank icons after iOS 26.0.1 update on iPhone

After installing iOS 26.0.1:

Certain apps that worked perfectly until now, are not opening.

When I try to open the app, it looks like it’s opening, and I can see the cover photo of the app, and the little upload symbol spinning, but that’s it; the app won’t open.

Another issue: a few other (what used to be) app apps, turn into white squares either geometric shapes; and the “name” of the app is gone.

Please Advise.
