QuestGamesOptimizer crash ?

You can try to uninstall and reinstall it.

QuestGamesOptimizer doesn't appear in Unknown Sources or you can't reinstall it ?

If you uninstalled QGO to install a newer version of QGO and QGO is not present in the Unknown Sources, it appears that sometimes, QGO is not completely uninstalled by Meta Quest software... It sometimes occurs on games and app...

You have to force uninstalling QGO by entering this ADB command in SideQuest : adb uninstall com.anagan.qgo. And then, install QGO as usual.
