The <code>MTLTextureUsageRenderTarget</code> in the error shows that this is a Apple's Metal issue.

First of all, disable Auto Graphics API then change iOS Graphics API to OpenGLES2 or OpenGLES3 in Unity's Player Settings. <img src="https://i.stack.imgur.com/mYaxM.png" alt="enter image description here"> 3.Update to Unity to the latest version of Unity if #1 and #2 fail.
