Contao 4.11 Install Errors

[ally1]

Hello Everyone,

I just tried installing Contao 4.11 but it won't happen. There's a Composer error, which stops it. I've attached a screenshot of what keeps happening.

Any help would be much appreciated.

Thanks,

As of Contao 4.11, PHP version 7.3.0 or higher is required.
