Bug Reflection Probe Baking causes "maximum ps_5_0 sampler register index (16) exceeded" error

Unity 2020.2.0f1 and HDRP 10.2.2

So, I have a shader made in the shader graph. It works just fine, no errors in the inspector tab, nothing wrong in the scene itself, it looks and works as expected. But as soon as I bake any reflection probe that touches an object with this shader I get:

"Shader error in 'Shader Graphs/PasteYourMaterialNameHere': maximum ps_5_0 sampler register index (16) exceeded at line 10238 (on d3d11)"

Or

"Shader error in 'Master': maximum ps_5_0 sampler register index (16) exceeded at line 3783 (on d3d11)"

Or both.

And the reflection probe captures this object as completely pink (a.k.a broken shader). The shader gets the same error listed in the inspector tab after that but otherwise continues to work just fine. Of course, I can hook up a sampler state node to a few of texture samplers in this material, bake a reflection probe (bakes just fine in this case), then delete the sampler state node and go on working. But this is not how a normal workflow is supposed to look like, correct?

Thanks!

 

Same here.

 

I have a similar issue but maybe related? My builds worked fine until I started lightmap baking. Then all of a sudden, I'm getting this error when attempting to build to android.
