Just to clarify, your camera is blurry in regular mode and not in pro mode is that correct?
Can you please provide me with the troubleshooting steps you have tried?
Are you using the stock camera app?
Do you experience these symptoms if you test your device in safe mode?
If your phone is misbehaving, it's possible that a third-party app is causing the issue. To figure out what app is acting funny, you can use the Safe Mode feature. In Safe Mode, your phone won't run any third-party apps. This allows you to easily identity and remove the app that may be causing the problem.

You're welcome. Please keep me posted if I can be of any further assistance.
