Cannot Deploy developer Test Version to my IPAD

I never had problems to test IPA Files on my IPAD. I created a

Developer Certificate (with MAC Keychain), then I exported to .p12 certificate (There i was using a Password)

Then I created Provisioning Profile and included my IPAD with UUID number I checked everything in the ipa File. Device is included

When i now use Itunes to install the Application it stops at 45% and the icon stays transparent.

When I use the same Certificate for Distribution and use the corresponding Provisioning file. I can upload to appstore with Application loader.

I have an older IPA File from the same app ( 4 weeks older)  that is working

When i change the app in Adobe Animate ( just the actual certificate and the Provisioning File) it doesnt work anymore.

Please help. I am not able to test my Apps in IPAD (only Testflight is working with distributing versions to appstore)
