Mixed Conditionals.
British Council again writes:
Mixed conditionals
We can use mixed conditionals when we imagine a past change with a result in the present or a present change with a result in the past.
1. Past/Present
Here’s a sentence imagining how a change in a past situation would have a result in the present.
So the structure is: If + past perfect >> would + infinitive.
2. Present/Past
Here’s a sentence imagining how a different situation in the present would mean that the past was different as well.
And the structure is: If + past simple >> would have + past participle
