App installed one year ago doesn't open anymore

A year ago I bought a DJI drone and installed the DJI Fly app on my Android 13. Note that this app is not available on Google app store. It can only be installed with an apk, downloaded from DJI website. As it turned out, that specific version of the app was affected by a rather useful bug, which is not the topic of the discussion. Hence, I never updated the app. A few days ago the app stopped working. When I tap the icon, there is a window opening, but it closes itself a moment later, without showing the app main screen. No error message is shown. It crossed my mind that exactly one year passed from the installation date, which leads me to believe in some *planned obsolescence mechanism*. So, I turned on Airplane mode and reopened the app: same behavior (note: so far, I was always able to open the app and fly the drone even when there was no cellular connectivity). A few months ago a friend of mine also experienced something similar, although at that time I didn't realized that exactly one year passed by his original installation. Apparently, the only solution would be to update the app, thus losing the *bugged capability*. Regardless of the lost capability, this was a wake up call to me in that I realized that I don't own the drone. If tomorrow DJI decides that my drone model must not fly, my days using the drone are going to be numbered, which makes me uncomfortable. I have attempted to: * uninstall the app from the launcher, and reinstall it (the same version). The installation fails with the following message: app not installed as package appears to be invalid. * I have downloaded Android's platform tools. Then, I uninstalled it with adb shell pm uninstall --user 0 dji.go.v5 and reinstalled it with adb install path/to/apk. The installation is successful but the app doesn't work, with the same symptoms as mentioned above. My questions are: * (not really important, but out of curiosity) from a developer standpoint, what mechanism could implement this *planned obsolescence* behavior? I believe there could be some files stored on the device, because the app won't start even when using Airplane mode. * I though uninstalling with adb was going to remove all data associated to a particular app. But since the app doesn't work after the new installation, this can't be right... What else can I attempt to get that specific version of the app working again? Note: format the phone is the last thing I would want to try, as it would take me a few days to get it fully operational again. But if nothing comes to mind, I might be inclined to try... **EDIT:** adding logcat about DJI application:
