I've tried all the commonly suggested troubleshooting tips for unresponsive or problematic apps (from the simple deleting cache to the drastic factory reset). Real Racing 3, Mobile Legends, and Darkness Rises are the 3 games that currently do not wish to load past the startup screen. For the most part, it seems to be caused by a server timeout. This also seems to be in no way related to my network connection, due to the fact that pubg mobile starts and runs smoothly. I'm always running the latest software and this problem has been plaguing my Galaxy S20 Ultra since approximately fall of 2020, first noticed with Mobile Legends (a game I played quite often for a couple months prior to this).
