This can occur when there is too many background processes running. 1- please reboot your device. 2- go to the Play Store and update the OnePlus Launcher (New Version at the moment). 3- check if you have the latest OS firmware for OnePlus Nord. It is since today in 10.5.11. If you have only 10.5.10 just download the new version using Oxygen Updater app from the Play Store to have your device fully up to date. Regards
