You cannot because Fast and Slow rings are reserved to Redstone2 new testing builds, Release preview is the same Redstone1 of production. Two totally different branchs.
So only way is restoring to official build via Windows Media Tools if you got a pc, WDRT if you got a Lumia

try checking for OS updates again and also for app updates
What OS version are you on? You can check in settings > system > about > OS build
