TESTFLIGHT only shows a blank window with our logo

Hi, we have a problem after uploading to IOS.
Testing in flightest only shows this window and doesn’t continues to show the app.

I read on the forum that i should debug on Safari but the problem is that when i open the app it doesnt show me any option on safary so I debugged on other platform.

It shows an error message that I don’t know from where to start investigation

It is the same app we upload to ANDROID without errors

Here is the log i received:

Did you test a debug build of iOS on a local device? You can use Safari to watch for errors there.
