Unity as library crash: Texture at colorAttachment[0] has usage (0x01) which doesn't specify MTLTextureUsageRenderTarget (0x04)

Wikitude Professional Edition version: 9.4.0

Not using Extensions or SDK for Smartglasses

Unity 2020.1.13f1

XCode 12.4

On IPhone XS, iOS 14.4, iPhone 11 Pro, iOS 14.4.1

Own project

Unity Packeges:

Wikitude
ARFoundation
Firebase
Unity UI Extensions (Particle System)
ARFoundation, plane detection.

We export the Unity project and then integrate it as library to an existing iOS app project in XCode.

- The application opens in the main view (native)

- Press a buton to load Unity view.

- Loads and crashes:

validateRenderPassDescriptor:702: failed assertion `Texture at colorAttachment[0] has usage (0x01) which doesn't specify MTLTextureUsageRenderTarget (0x04)'

We have tried:

- Disabling metal validation

- XCode setting: OpenGL ES instead of metal

- Crashes after loading the scene with wikitude camera (no use of ARFoundation in this scene), after a scene where we check ARFoundation support and camera permission on the device.

Note: the integration was working until two weeks ago.
