Question Tangent space issue upgrading graph from 2019.2 to 2019.4

Hello,

I'm trying to upgrade my project from 2019.2 to 2019.4 and the first thing I noticed is that my shaders from graph using Tangent space Position node are broken.

I tried to recreate a basic graph on both versions doing the same thing and I get very different results.

Does anyone know what could be the reason and how I can fix this? (it also appear on 2019.3)

Thank you in advance

2019.2

2019.4
