How to get past the pre-Launch phase?

I have no idea how to proceed with getting my app out. After submitting everything, the Pre-Launch review came back with 1 error (crash on a certain phone type) and multiple warnings. Said fix before rolling out. I had no idea how to fix these, but currently I can’t even find this list of errors, the notice now says ‘full rollout started’ but the status is ‘in review.’ I’m trying to do ‘open testing,’ because almost the only way I can get the app to people to test is to have it available for Play Store download. It is definitely not yet on Play Store. What do I need to do?

Just wait.
The app is being reviewed by google side. Soon it will be live. Some times it takes days also, sometimes hours only. So just wait till completion of review.
