Every Unity project with ARKit doesn't open in Testflight

Even when making a completely fresh Unity project, if I include ARKit and upload it to testflight, when I open it on my ipad it says 'Couldn't Load App'.

If I don't include testflight the app opens fine. If I build the app directly to my ipad the app works fine. It opens if I set ARKit to 'optional' but then the AR doesn't work. I have included a camera and location usage description so it's not that.

Really not sure what's going on, any help would be massively appreciated!

If I don't include ARKit the app opens fine.*

Since Unity is the one creating the project that isn't working, you should also bring this to the attention of Unity's support.
