Who can suggest what to do for me? The problem is as follows: I bought a MacBook Pro 2018 A1989 with the Monterey operating system and wanted to install Ventura.

I didn't update Monterey online because I had Ventura on a flash drive. I pressed the Option key and turned on the MacBook, selected my flash drive, then the recovery menu appeared, and I entered Disk Utility. I erased the internal SSD.

Then I exited Disk Utility, selected OS reinstall, but a window appeared saying there is no permission to boot from an external disk. Then I read online that this laptop has a T2 chip, and security must be disabled.

I went to the Startup Disk Utility, but I can't access the menu because it requires entering the OS administrator password, which I can't do because I erased the operating system.

Then I tried to restore the system over the Internet, but I can't do it because it gives an error that there is no connection to the server. In other words, it's a catch-22 - I need to disable security, but I can't do it because I erased the operating system, and I can't update online because it gives an error."

Typically there is no call for erasing the SSD before you upgrade especially if you have a active user account/data.

Not sure what to tell you—

if you have access to an Apple Store or AASP they can help you get a macOS back on the drive.

I would bring proof of owner ship of the Mac with you to the store.
