Hello Srikrishnan12,

We would like to see how we can help you with your keyboard freezing unexpectedly. Does this happen in all apps or only specific ones? Have you added any third party keyboards to your iPhone. If so, please remove them and test to see if the issue persists with the steps in this link: Add or change keyboards on iPhone - Apple Support

"Add or remove a keyboard for another language

1. Go to Settings  > General > Keyboard.
2. Tap Keyboards, then do any of the following:

• Add a keyboard: Tap Add New Keyboard, then choose a keyboard from the list. Repeat to add more keyboards.
• Remove a keyboard: Tap Edit, tap  next to the keyboard you want to remove, tap Delete, then tap Done.
• Reorder your keyboard list: Tap Edit, drag  next to a keyboard to a new place in the list, then tap Done."

Cheers
