Safari freezing and crashing

Hello MaAmritNirava.

Thank you for using Apple Support Communities. Sounds like you need some help with Safari. If so, we'd like to recommends some steps you can try to see if that helps sort this out. First, try to force close the app. This usually helps refresh things. Follow these steps here: Close an app on your iPhone or iPod touch - Apple Support

On iPhone X and later:

1.) From the Home Screen, swipe up from the bottom of the screen and pause in the middle of the screen.

2.) Swipe right or left to find the app that you want to close. 

3.) Swipe up on the app's preview to close the app. 

You can also try clearing your Safari history. This step usually has a positive result for when facing Safari issues:

To clear your history and cookies, go to Settings > Safari, and tap Clear History and Website Data. Clearing your history, cookies, and browsing data from Safari won't change your AutoFill information.

Also, double check to see if your iPhone is using the most latest version of iOS 16. If you have a pending update, we recommend that you install it. Keeping your device fully update can help resolve various issues. Just in case, this resource can guide you through the update: Update your iPhone or iPad - Apple Support

Thank you for using Apple Support Communities. Cheers.
