Yesterday night I noticed my infuse wasn’t opening up, so I uninstalled and reinstalled and it was working again for a few hours. Now I’m having the same issue again. It tries to open up I see the logo but it sends me back to homescreen all the time. Even restarting the phone didn’t fix the issue. I’m using an iPhone 13 Pro Max on iOS 16.2
I’d say delete it again (don’t off load, delete it) and re download it again. Sometimes the Apple servers garble the download.
If that doesn’t work there might be something corrupted with your iCloud data
