I have the same problem!
you found a solution?

[jacobokoenig]

I went through a lot of errors that I solved in different ways, If I am not mistaken, this one I solved by including Camera permissions in the plist.info file.

Key : Privacy - Camera Usage Description
Value : $(PRODUCT_NAME) camera use [Or whatever other description you want]

Let me know if this works.

Hello, I have this same problem, I reported full details here:

https://forum.unity.com/threads/vuforia-augmented-reality-black-screen-when-accessing-android-camera.265335/#post-3673327

and here:

https://forum.unity.com/threads/vuforia-augmented-reality-black-screen-when-accessing-android-camera.265335/#post-3673429

But I still continue with problems.

@jacobo360, what do you mean with:

I went through a lot of errors that I solved in different ways, If I am not mistaken, this one I solved by including Camera permissions in the plist.info file.

Key : Privacy - Camera Usage Description

I opened my plist.info file and I don't know how to fit what you said in the file. The format seems a lot different:
