Rig seems good in frame 0, but goes wonky when trying to ani

So I created an alien character for a spot and I rigged him to the best of my ability and everything seemed fine in frame 0. When I started to make keyframes I noticed his arm seemed to ignore or just go crazy dealing with kinematics. Checked all the parenting and even rebuilt the bone rig for the arm. Still crazy, erratic movement.
I am theorizing that there may be a layer binding issue. Can a layer be bound to two different bones though?
Rechecked the layers as well as the bones and found no issues. The right arm just seems to want to raise and the forearm wants to fold in. the hand bone doesn't seem to be affected by this.
Now wondering if the angle restraints are causing the issue.
Thoughts?

If can share the file, please do.
I can help more if I see what your working on.

Here's the file I'm working on. The problem is only evident when I move the arm after frame 1 in the timeline.

To fix, take the angle constraint off the right shoulder.

Cool rig! Hope you don't mind, I downloaded it to take a look at how it was built. I'm in the learning process.

Hi,
Sorry for such a late reply. I'm in NY and we had a storm that knocked out the power and internet.
I took a quick look. The rig is behaving just as you set it up. The kinematics are not working. Why I don't know right now. You can get around it by holding Alt. When I get time I will look into it some more.
I would change the forearm angle constraint to -90, 120.
I would bring the arms to the front of the character.

Tried that and the only difference was that the whole arm now moves around in erratic circular movements.

Doing the Holding Alt thing for now. Good idea, hadn't crossed my mind.
Tried lifting the angle constraints on the shoulder as jezjones29 suggested and the whole arm was then erratic. Ugh.
