It appears that most of the apps are crashing as soon as you open them. You can check a few things to begin troubleshooting the issue:
(1) Try and Force Restart your iPhone EXACTLY as shown below and see whether that resolves the issue:
- Press and quickly release Volume UP button
- Press and quickly release Volume DOWN button
- Press and Hold the SIDE button until an Apple logo appears and then release the Side button (Can take up to 20 seconds. (DO NOT release Side Button when invited to Slide Power OFF).
(2) If the above does not work then - Double check to ensure that you have ample free storage space available on your iPhone. Open Settings ➡️ General ➡️ About ➡️ Available: Here you will see the available storage space on your iPhone. You should maintain at least 15GB - 20GB free storage space for the iPhone’s efficient operation.
(3) If the above does not apply then - You may have a poor battery condition which cannot provide sufficient power for peak performance. What is the Battery Health of your iPhone? Open Settings ➡️ Battery ➡️ Battery Health and let us know which percentage you see for Maximum Capacity. Also note what is written under Peak Performance. If your battery's Maximum Capacity shows a value of 80% or less, then it has gone through its lifecycle and therefore should be replaced, according to Apple.
(4) If that does not apply, then contact 👉 Official Apple Support OR you can always get your iPhone examined at the Apple Store 👉 Genius Bar Reservation and Apple Support Options or at an Authorized Service Center for further diagnosis and evaluation.
