Updating my Sticker Pack from 2020 and having an Arm64 issue when Validating

I am updating my Sticker Pack that I've updated dozens of times before, but it's been a while. (Spring 2020)

I have searched everything, and tried a lot of variations, but I keep getting this error when I validate the archive:

When I change the UIRequiredDeviceCapabilities to "arm64," from "armv7" (in Target/App/Info/plist, I think) then I get these errors:

I have also tried removing any items from UIRequiredDeviceCapabilities and that didn't work.

**What else am I missing? **

I have also tried changing various deployment targets and different Xcode version compatibility settings.

This is the option I have for Build devices, but I also tried with my own iPhone plugged in and that made no difference:

I am not a developer, so please spell out exactly where I can find what I need to change!

Also, how maddening is it that these Xcode warning screens have unselectable text for copy/pasting?? I can select text in the screen shot, but I shouldn't have to. Also cool that the error message links to web pages that are dead.
