I cannot Upload my App on the Appstore-Please help me

Hello , i'm a developer , i heve to to publish an app on the appstore for the first time with a publisher.

They have to test the game , so they told me to follow this guide: h ttp://help.buildbox.com/en/articles/1639174-appsflyer-analytics-ios

To integrate AppFlyers and GameAnalytics on my project.

Ok , followed the guide , and tried my app on my Ipad air 2 with ios 13.5.
It works fine.
So i have to upload the app on the appstore to make the testflight.
I'm trying to upload the app on the appstore , but both with app loader and Archives organizers, it give me errors , here's the log :

So ,i think the first error is about the icon format , it's a .png and it could be solved using a .jpg files.
But the other errors ,i dont know how to solve them...

I realy dont know how to go on in the uploading process,i've tested the app on my ipad with Ios 13.5 and it works fine , why do i have all those errors if the build is the same ?


Thanks
For the first 2 errors:
ERROR ITMS-90717: "Invalid App Store Icon. The App Store Icon in the asset catalog in 'BBPlayer.app' can't be transparent nor contain an alpha channel."
ERROR ITMS-90725: "SDK Version Issue. This app was built with the iOS 11.2 SDK. New apps for iPhone or iPad must be built with the iOS 13 SDK or later."

App icons can be png. But the size must be exactly the required one.
How did you create the images ?

For the second, just follow instruction and use 11.3 SDK (that will be the case with Xcode 11.5)
