Hello!
Since your case seems to be urgent, here are the necessary instructions to regain access to your iPhone:
Does the device have iOS 15.2 or later installed? If so, it can be reset without a computer. To learn how, please see this: If you see an iPhone or iPad unavailable message or Security Lockout screen - Apple Support.
If it doesn’t have iOS 15.2 or later installed, then you will need a computer to reset the device. See the following Support Article for instructions: If you forgot your iPhone passcode - Apple Support.
In the future, consider starting your own thread here for the best possible assistance and focus on your issue.
Have a nice day, and good luck!
