You can try those:
1. Clear the game's cache and start the game.
2. If still black screen after clearing the cache then force close the game and try again 5 times (the game might take 1-2 min to start on the first run)
If you've any game boosters please deactive them.
If none of those work you'll need to make a fresh install of the game by uninstalling the old and installing the new mod, link your account before doing so.
Case nothing works at all, then please send me a video in private of the issues and doing the 2 steps i mentioned. You can upload the video to any hoster you prefer but ig you can upload to GoogleDrive or any other that has streaming will be better.
