@CONSOLE Alfredo, Cloud Administrator, Thanks for posting in Q&A.
From your description, I know you want to uninstall apps on Android device but failed.
Based on my research, if you want to uninstall one app, you can just assign group under Uninstall and after sync the app will be uninstalled.
The reason why you failed to uninstall the app and got error message is probably you not only add All Users under Required but also add some user groups Under Uninstall, that may cause some conflict, so if all the users have installed the app successfully, you can remove All Users under Required and just leave the user group you want to uninstall under Uninstall and sync with Intune, the app may uninstall successfully.
Please try above information, if there is any update, feel free to let me know.
