Is HDRP for 5.10 template will be available any soon? This version of SRP available only in 2019.1b and above, but still maybe you have a preview version too. Right now, I got these errors:
Shader error in 'New Amplify Shader': 'InitBuiltinData': cannot convert from 'float' to 'struct PositionInputs' at line 978 (on d3d11)
This was just an empty HD Lit shader in HDRP 5.10 on Unity 2019.1.0b10
