Image Tracking Primitives Causing Lockup

Hey, as stated in the title using Unity Virtual Buttons are locking up android devices, I am not sure if I should place this here or in unity. I have tested this on "OnePlus 5" and "Xiaomi Redmi Note 7". I have enabled / disabled ARCore, include ARCore library, Device Pose Tracking, using different image targets and a number of combinations of options however whenever the app starts to track any marker with any primitive or virtual button with a primitive it locks up and the screen then jitters back and forth between two frames, sometimes it causes the whole device to reset. It does work in the unity environment simply using a webcam. I even created a new tracking image to test with a single primitive square to spawn and it locks up. If  there is no primitives such as having a single virtual button without any child primitives to render it runs fine (but obviously pointless). Any advice? Thank You.

OK I have found the issue, it was with the LWRP. unsure if it's with SRP in general but after removing LWRP and changing all materials to a standard shader it now works.
