You need to first have a look how the primary is held on the baffle tube. If there is a retaining ring in front of it make sure it's not screwed on tight. If it presses on the glass of the primary if will stress the glass. Issues with secondary mirrors usually show up as trefoil shapes in the stars. If the secondary baffle tube is made out of aluminium and it's pressing on the side of the glass as well it could stress the glass.

So here's a couple of things you can start looking at mechanically.

PS: I googled your scope to see how it's made inside and there is a small retaining ring on the primary. Worth checking that first.
