Sorry I don't have an answer, but a related crash started for me in Beta 5 and remains a problem in Beta 6. I have a UIViewRepresentable in a slide-over view I'm bringing up from the bottom. It works on some views but crashes consistently on another libc++abi.dylib: terminating with uncaught exception of type NSException ** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[MTLDebugRenderPipelineState removeUsedRenderTarget:slices:]: unrecognized selector sent to instance 0x7ff22b510800'
