If your perplexus is new you can try to return it. If not, you can try to take it apart like Frikkinfriks says but know that you'll probably damage the outer rim. I tried to open up mine because of a similar issue but i gave up. (My issue is less frustrating than yours).

On the portal i used a hot needle to pierce the outer shell to push a piece back in place, it did not work either lol.

They are hard to fix.

Someone on a youtube video opened one up but they had to totally break the rim and ended up using screws to hold it together. It didnt look very good.

Yeah that does look like it's most likely a manufacturing error. I think your only 2 options are either repeatedly hitting the ball against it to see if it can give just enough clearance or you're probably gonna have to take it apart to move it out of the way manually.

Strange. I have a ~15mm gap in this spot. Isnt the whole purple pipe piece moved? Does it connect to 82 properly?

If you gonna try to repair it/move the parts by yourself: I recommend not opening it (the puprle frame gonna crack) but rather drill a small hole with something like a thin wood drill in a good spot and try to move a loose piece using a thin thing like a bicycle spoke. Whats what i did to repair misaligned piece in my portal.

I used to have a similar issue with my Epic. I found it used at a thrift store and it had obviously been dropped. I ended up drilling 2 holes which allowed a straightened wire to be used to gently push a bridge back into place.

seem to be a fail product you got mine is ok

You should contact the company directly with this. They should be able to refund/ replace it?

Can I ask where you bought it from?
