Do not assume that a Solve invitation guarantees you have passed the full resume screen.

McKinsey can use Solve as one input within the broader recruiting process, and the sequence can vary by office, role and recruiting cycle.

The useful conclusion is simply that you have an active assessment step to complete. Prepare for it and continue treating the rest of your application as part of the evaluation.

If you want to understand your specific process, use the instructions in your invitation or ask recruiting. Avoid trying to infer an interview outcome solely from receiving the assessment. For more detail, see the McKinsey Solve guide.

I got Solve and still didn't get an interview, so I would definitely not treat it as a pass.
