If you mean by Apps getting uninstalled or removed from the screen and you have to reinstall to use the app then it is your device issue.
I had the same issue on Lineage os but after reflashing the ROM it is working fine. You can try the same.:good:
i add folder's of apps on home screen like of social apps and google but every morning all folder's get deleted and i can see apps how i saw home screen after fresh installation. home screen folders and widgets gets removed every morning.
