iphone 11 and iso 17.5.1 issues

Since I update to IIOS 17.5.1 on my iphone 11 it now randomly shuts off when I open an app. I could restart it 3 or 4 times before it connects to wifi and blue tooth. It may be ok for 10minutes or an hours, then when I go to open any app its switches off again. Has anyone else had these problems and does anyone know if apple is going to address these issues
