We have even created a new build today of a version which is already live on the App Store and now this new one is crashing as well as the rest, which does not make sense as no other changes were introduced.

We also use bitrise for distribution and these builds are working fine, it is just when those are going to TestFlight that it crashes.

Hope I have been clear and thanks a lot for the help!
