Obtainium tries to find your architecture apk if it's avaiable, this is the first release with architectures APKs so probably it's trying to download the wrong one.
Uninstall Pokey and install it again using Obtanium
I did that and still the same error.

With Obtanium? Did you try to download it manually?
Just tried downloading manually from github releases page. It installs but the app crashes on load.
